From University Lecturer to Chief Academician
Chapter 631 Covalent structure of inner electrons, a new direction in materials science!
After having enough materials, the measurement of moissanite progressed very quickly. It only took about three days for Wang Hui's laboratory to issue a very detailed measurement report.
The laboratory will continue to conduct subsequent measurements, but these are studies that require long-term follow-up.
The current report is very detailed.
The Super S-Wave Research Base quickly received the report, and Wang Hao also summoned many people to discuss it.
The detailed test report of moissanite is very unusual. It is similar to the previous report and shows abnormalities in physical and chemical properties.
"The abnormal physical properties are mainly reflected in the special high melting point, high toughness, and high hardness."
"This data goes beyond conventional structural logic."
From an atomic structure analysis, no matter how stable the atomic arrangement of silicon carbide is, the physical properties it exhibits cannot exceed those of diamond.
The covalent composition of diamond's carbon atoms is extremely perfect.
Carbon atoms have four covalent bonds.
In the atomic structure of diamond, carbon atoms are connected to each other in a tetrahedral bonding manner to form an infinite three-dimensional skeleton. It is a typical atomic crystal. Each carbon atom forms a covalent bond with four other carbon atoms in an SP3 hybrid orbit. Form a regular tetrahedron.
If you want to go further, you can only create graphene-like substances, which cannot be measured by simple bond composition.
The atomic structure of silicon carbide, which is composed of two elements: carbon and silicon, is relatively stable. However, silicon atoms have only two covalent bonds on average. The atomic structure of the silicon carbide formed is obviously incomparable to diamond.
Because of this, diamond has a Mohs hardness of 10 and silicon carbide has a hardness of 9 to 9.5.
The hardness of moissanite is 1.5 times that of diamond, and it can no longer be explained at the level of atomic ordering structure and molecular composition.
"Chemical properties also exhibit anomalies, reflected in chemical reaction requirements that exceed energetic logic and the release of energy."
"Like, burning."
"Silicon carbide combustion releases energy intensities beyond specifications, 25 to 27 times greater than conventional silicon carbide combustion."
"This is obviously not normal."
Simply put, it means that the heat released during the combustion process exceeds the specification.
The combustion of carbon silicon spar is the reaction of elemental carbon and elemental silicon with oxygen, which mainly generates carbon dioxide and silicon dioxide. If the reaction is not sufficient, carbon monoxide, silicon trioxide and other substances will also be generated.
Combustion is a fixed chemical reaction with a fixed chemical equation. The final heat generated can also be calculated based on the overall energy loss.
Now there is an energy release that is more than 20 times higher, and explosive flames and high temperatures are also formed in the process, which is obviously far beyond the normal scope.
"Why is there such a situation?"
At the discussion meeting, Wang Hao explained the measurement report of moissanite and also asked everyone questions.
Participants included people from the theoretical group, several scholars in the fields of physics and chemistry, and several leaders and directors of the research group. The latter just attended the meeting and listened to the content. It is difficult to give professional advice.
Yang Zhifen and Lu Zhen are both excellent experts in the fields of molecular chemistry and atomic physics.
Many people also looked at them.
In the fields of molecular chemistry and atomic physics, Yang Zhifen and Lu Zhen are the top experts present, and they can put forward very important opinions in the professional field.
But the current situation is that the content of the test report has gone beyond the normal scope.
Yang Zhifen and Lu Zhen both frowned, completely unable to understand why such a situation occurred.
Wang Hao also looked at the two of them expectantly, and at the same time looked at others expectantly. He held a targeted discussion meeting with the purpose of analyzing what specifically happened.
Perhaps for others, if they want to know the underlying reasons, they still need a series of experimental measurement results before further analysis and derivation can be carried out.
Wang Hao only needs an idea, a correct idea.
While many people were lost in thought, Wang Hao was leisurely playing with the 'big diamond' in his hand.
Among the manufactured moissanite, there are many 'big diamonds' forming a regular polyhedral structure, the largest of which is even close to 9 centimeters in diameter.
The one in Wang Hao's hand is not the largest, but it is the most beautiful among them. It seems to be mixed with other elements, making it emit various colors of light when illuminated by light.
He put the diamond in front of his eyes and looked at it carefully, and couldn't help but sigh, "It is indeed beautiful and suitable for jewelry..."
"Give it to Yingxue!"
Wang Hao has already made the decision to enrich himself, while others are thinking about the reasons for the abnormal physical and chemical properties of moissanite.
They quickly grasped the important point - the composition of atoms!
The analysis of the physical and chemical properties of any substance must ultimately be attributed to the composition of atoms and molecules. However, the physical and chemical properties of carbon silicon spar are so excessive that they cannot be explained by 'molecular bonds', and can only be attributed to anomalies in the atomic composition. .
"No matter how it is constructed, molecular bonds cannot have such a stable structure, nor can they have such excessive chemical properties."
"It can only be an abnormality in the composition of the atoms, or it can be understood that some kind of change has occurred in the atoms."
Wang Hao recognized this conclusion.
The discussion will continue along the direction of research, and the theoretical team will consider what changes will occur after the electron layer of atoms is stripped away.
"The phenomenon of upgrading can be ruled out."
Helen explained her opinion, "Neither the carbon atoms nor the silicon atoms have been upgraded, and at the same time, the atomic nuclei have not changed."
"When we studied the upgrading of elements, we have discovered that atoms that return to the normal environment after magnetization will also return to their original state."
After Helen finished speaking her opinion, others started to discuss it, but no matter which angle they studied it from, they could not come to a conclusion.
This is because conventional physical and chemical content can no longer explain such an abnormality that exceeds the standard.
Ding Zhiqiang whispered to Chen Mengmeng, "It may be that some kind of change has occurred that is impossible to conventionally exist."
"Using conventional physical and chemical knowledge to discuss undiscovered phenomena will not yield results."
Chen Mengmeng nodded with deep sympathy, then his eyes lit up and he said, "Could it be like this? For example, carbon atoms and silicon atoms are combined together?"
"Or, the nuclei of carbon atoms and the nuclei of silicon atoms are combined together."
"They don't form covalent bonds on the outside, but on the inside..."
Ding Zhiqiang followed his thoughts and asked with confusion, "How is it combined? Two atomic nuclei..."
He couldn't figure it out.
At this time, Wang Hao's eyes suddenly lit up, and the correct feedback appeared in his mind, and he immediately said, "Is there a possibility that the carbon and silicon elements are not bonded together by covalent bonds? Or is it not the action of outer electrons, Molecularly bonded together?”
Chen Mengmeng was stunned when he heard this, and couldn't help but admired, "Teacher Wang and I thought of getting together."
"It really is."
Ding Zhiqiang was full of admiration for Wang Hao, "We just thought about it, and Teacher Wang said it. He must have thought it earlier than we thought."
The discussion continues.
Two atoms are not held together by molecular bonds, so how can they be held together?
Most people are frowning.
Chen Mengmeng thought of a possibility. She immediately raised her hand and said, "Is this the case? I'm just telling you what I think..."
She said hesitantly, even she herself felt that the idea was too scary.
Wang Hao said encouragingly, "This is a discussion meeting. If you have any ideas, please speak out."
"All right."
Chen Mengmeng said, "That's right. Strong S waves will strip off the electron layer of atoms, so is there a possibility that after the electron layer is stripped off, the carbon nuclei and silicon nuclei in close proximity will be affected by the strong annihilation force field in a fixed direction, so that Some special form of combination..."
"Like the twin stars in the universe?"
"After returning to the normal environment, the electron layer returns and forms a stable structure around the two atomic nuclei."
"In this way, the silicon carbide molecule becomes a special atom with a carbon-silicon dual-nucleus structure, and the outer electrons are connected to other similar special atoms..."
After hearing Chen Mengmeng's explanation, everyone else's eyes widened in shock, and they subconsciously felt that it was 'impossible'.
"There is no such substance in nature."
"Two atomic nuclei are close together? The nuclei, which are also positively charged, generate a very large charge repulsion, and will soon be separated."
"It's impossible to form a stable structure like this!"
Wang Hao frowned and thought. He no longer played with the big diamond in his hand, but said, "Maybe the nuclei don't need to be close enough, but just closer?"
"Silicon carbide molecules form covalent bonds through the interaction of outer layer electrons. The electron layer is stripped off during the return process, which may form a special stable structure, making the molecular bond more stable."
"For example, the inner electrons also participate in the formation of bond positions..."
What he said made his eyes light up, and he confirmed his thoughts.
Others think along the lines.
Yang Zhifen put down the pen in his hand, raised his eyebrows and asked, "The inner electrons do not participate in the composition of chemical bonds. Moreover, even if this makes sense, the two nuclei need to be close enough to be possible, but..."
Helen smiled and said, "Professor Yang, what you are talking about is not a problem at all. What we study is not simple chemistry and physics, but special reactions involving strong S waves."
"Strong S waves are directional strong annihilation force fields, which will subject the atoms themselves to a unidirectional annihilation force field. During the reaction, the interior of the atomic nucleus will also be greatly affected."
"If the intensity of the strong S wave is high enough, the atomic nucleus will be pulled apart and the positive charge of the proton will be stripped away, and then degrade into a neutron."
"So, we have enough conditions to bring the nuclei close enough."
Everyone else looked at Wang Hao.
Wang Hao affirmed Helen's statement, "Yes, the special characteristics of strong S waves determine that they will have a huge impact on the nucleus."
"When the electron layer is stripped away, the electromagnetic interaction of the protons in the nucleus will also be affected, enough to bring the two nuclei close..."
…
The symposium on moissanite structure is over.
Many people were still talking about the content of the meeting. Wang Hao confirmed Chen Mengmeng's idea and also explained the special molecular structure of silicon carbide.
Carbon and silicon atoms are not combined by chemical bonds generated by outer electrons, but when the nuclei are closer, they almost form a single atom.
It can be understood as two different circles. Conventional molecules are two circles stuck together, with a common intersection point, which is a chemical bond. Now, one side of the two circles is stacked together, resulting in ' The total area' forms a double circle structure.
Such a structure can no longer simply be called a 'molecule', nor can it be called an atom, but a special structure between atoms and molecules.
The definition given by Wang Hao is ‘covalent structure of inner electrons’.
The covalent structure of the inner electrons explains the detection results of carbon silicon spar.
For example, ultra-high physical properties.
The inner layer of electrons has a covalent structure, and the covalent bond formed is more stable. There may even be several 'inner layer shared electrons', making the structure more stable.
When the molecular structure is more stable, more energy will inevitably be required to split the molecules. During the process of splitting the molecules, there will also be greater energy loss, which will naturally generate greater heat.
To a certain extent, the combustion process of moissanite even sidelines nuclear reactions.
…
The 'covalent structure of inner electrons' discussed at the meeting has not been completely determined.
Although no one doubts Wang Hao's statement, further testing and research are still needed to prove the conclusion.
However, the research team does not need to prove it.
They are not specifically studying molecular issues. They are studying the properties of the super-S wave region. Regarding the discovery of carbon silicon spar, what needs to be considered is whether there are other chemical elements and substances that can form the same ' Covalent structure of inner shell electrons'.
In other words, it is whether other ‘new substances’ can be produced.
this is very important.
If more substances similar to moissanite can be discovered, new leaps and bounds will be achieved in the field of materials science.
Previous first-order elements have made leaps and bounds in materials science, and now the 'inner-layer electron covalent structure' makes it possible to create many substances with special physical and chemical properties.
Brand-new substances also represent brand-new material technology, which means finding a new direction for material manufacturing.
Moissanite has many uses.
Many people see moissanite and subconsciously regard it as a kind of jewelry similar to diamonds.
In fact, moissanite has the characteristics of colorless transparency, stronger hardness, toughness and special high melting point than diamond, allowing it to have a very wide range of uses.
For example, it can be used as a high-temperature and pressure-resistant lens.
High temperature resistant and pressure resistant lenses are widely used in various precision scientific instruments and equipment, aerospace engines, space technology and other fields.
There are also many industrial demands for high temperature and pressure resistant lenses.
This material can also be applied directly inside light pressure engines.
The performance of the excitation propulsion device of the light pressure engine determines the maximum light pressure thrust of the light pressure engine.
Among them, the performance of the condenser is a very important part.
A concentrator can be simply understood as a concave mirror, which concentrates strong light together to form a high-heat, high-pressure strong light source.
The performance of the current concentrators used in light pressure engines is relatively lagging behind, mainly because the manufacturing materials cannot withstand higher temperatures.
Generally speaking, as long as it is a transparent material, its high temperature resistance is limited, and it cannot keep up with metal and alloy materials.
The melting point of moissanite is more than twice that of the concentrator material in the light pressure engine, which can naturally greatly improve the performance of the concentrator and nearly enhance the performance upper limit of the excitation propulsion device.
