Chapter 1013 Knowing the result but not the reason
Doing scientific research is actually about finding the right path.

This is called 'pathfinding'.

All scientific research is about finding the right path after experiencing several failures.

You can't always be lucky enough to succeed just once.

Those who always succeed at one go are called imitators and plagiarists, copying and pasting.

What most scientific researchers have to face throughout their lives are countless failures.

Only by experiencing failure and understanding failure can you understand why you succeed.

Only by going through this process many times can the time of path-finding be shortened.

The more failures you experience, the more experience you will naturally gain.

In fact, whether a person is suitable for scientific research or academic work can be seen in three months.

Because most people do scientific research and academic work for no more than three months, their mentality will collapse.

You can't get through the nine-fold thunder tribulation period when your experiments never go smoothly, or the darkest moment of the path of destruction when the shit molecules in your thesis are transformed.

Many people want to pass an experiment in just one go and finish an SCI paper in a month. Does this situation really exist?
Yes, and there definitely is.

However, it is only after leaving the dark forest of academia that only a very small number of truly talented people can do it.

For those who have no talent or insufficient talent and want to make achievements in scientific research, is there any chance?

Actually, there are.

But you have to be able to endure loneliness.

To be conservative, don't think that you can't get experimental results if you haven't tried the wrong experimental direction 10 times, and don't think that you have no academic output if you haven't revised your first paper 50 times.

Because you should have no results, no output.

you deserve it!
Because you don't deserve it!
If you want to prove that you are an excellent graduate student or scientific researcher, you need time to fight loneliness, and you need to practice constantly to find your way, to try and error, to correct, and to polish.

In the process of countless path-finding, trial and error, correction and polishing, you will truly identify whether you are a person suitable for scientific research and whether you can have real scientific research output.

But most people give up at this stage. Many people lose their mentality after two or three months. This is the core reason why 99% of people say they are not suitable for scientific research.

Because of one’s nature.

Those who do not have great perseverance are not worthy of talking about scientific research.

Even if he is extremely talented, he still needs this mentality.

This is the basic condition.

Only when this basic condition is met can we talk about talent.

Therefore, whether it is Chen Weiping or Yan Dazhou, whether it is Que Duanlin or Chen Yiquan, they understand it too well.

What is the basis for scientific research?
The basis is, do you dare to take the step of finding the way?
Faced with the on-site explanation by Zhang Huiguo, the industry's leading figure, the young entrepreneur dared to question.

This is the nature of mind.

What is the focus of scientific research?
The key point is, can you find the direction clearly and calmly on a road full of fog?
This is talent.

Chen Yiquan looked at the disciple in front of him who had come personally from the leader of Western Shu Province to ask to be accepted into his school, and a bright light flashed in his turbid old eyes.

I didn't expect that it was only before I was buried that I found a disciple who possessed the basic skills, character, and talent.

When he accepted Qingyun as his disciple, he tested Qingyun's basic skills.

Originally, he wanted Qing Yun to give up.

After all, Qing Yun is not a student of Shu University, and this young man is the chairman of a large group. How can he have the time and energy to study? !

His purpose is nothing more than to get involved in the chemical industry, become his disciple, and then use the reputation of his own school to gild himself.

He might even use his connections in the sect to get them to work for him.

Chen Yiquan has seen many people like this.

Therefore, he, who can be regarded as a member of a powerful family in the academic world, is not prepared to sell face to his leader.

When you are older, you can throw tantrums.

Although Chen Yiquan also knew that Qingyun's college entrance examination results were excellent, with full marks in mathematics, physics and chemistry.

but……

College, not high school.

Especially the broad subject of chemistry.

The chemistry taught in college is a complete subversion of the chemistry taught in high school.

The chemistry knowledge you learned in high school and the conclusions you thought were extremely correct are completely wrong in the university chemistry system.

But what Chen Yiquan never expected was that after a difficult test, he found that Qing Yun's basic skills were very solid.

According to this guy, he had already learned the four major chemistry subjects of the chemical system in high school.

Chen Yiquan, who did not believe in superstition, examined inorganic chemistry, organic chemistry, analytical chemistry and physical chemistry one by one.

And Qingyun answered the questions fluently.

In the end, Chen Yiquan even felt that this kid was the epitome of gentleness, courtesy and humility.

too humble!

Too modest! How can this be said that he has learned the Dahua system in advance? !
The knowledge points examined by Chen Yiquan did not deviate from the scope of undergraduate university.

But Chen Yiquan felt that Qing Yun's depth of understanding of these knowledge points completely surpassed even his most proud disciple Shen Jun.

even……

He even felt that Qing Yun was qualified to sit down and discuss things with him.

Moreover, many of his academic views coincide with his.

This left Chen Yiquan helpless. He could only accept this disciple with ill intentions, who was obviously trying to gain fame, with a smile on his face, in front of provincial leaders, the richest couple in China, and the leaders of Shu University.

However, what he didn't expect was that he became a disciple in the morning, had the apprenticeship banquet at noon, and in the afternoon he was dragged to Jiazhou by this traitor.

The potential displayed by Qing Yun at this moment made him want to curse.

Not doing your job! It's simply not doing your job!
What kind of business do you want to start?
If you follow me to do scientific research, I guarantee that your child will be made an academician at the age of 40!
But thinking of this, Chen Yiquan could only smile bitterly and shake his head.

Damn, no one else needs it...

Emperor Yun, who was trying hard to keep his eyes 'clear', nodded and did not dwell on Zhang Huiguo's seemingly outrageous answer.

He knows the answer.

At this point in time, looking around the world, one by one, he can say that everyone is a loser in this field.

The reduction reactions of trichlorosilane and silicon tetrachloride are both endothermic reactions. Therefore, increasing the temperature will shift the equilibrium toward the endothermic side, which is beneficial to the deposition of silicon and will also improve the crystallization performance of silicon.

However, the reaction temperature cannot be too high in actual production, because silicon, like other semiconductor materials, has an optimal temperature for solid phase deposition.

Once this temperature is exceeded, the deposition rate decreases as the temperature rises. At the same time, the reduction amount of impurity B and P compounds will increase as the temperature rises, which will reduce the quality of polysilicon.

The temperature for the optimal solution for production and yield rate within 20 years is actually 1137°.

And he also knew why Zhang Huiguo and Hansmao's craftsmanship was controlled at 1100°.

After all, he is a reborn person, and his heart is actually clear.

The reason why the heat shield material of the reduction furnace is quartz glass is because the ideal working temperature range of the polysilicon reduction furnace found by foreigners is around 1100°C.

With the improvement of technology and the requirement for purity, this optimal temperature is slowly increasing.

Under the process conditions of the first generation of the modified Siemens process, that is, around the 60s, the rate at which silicon and hydrogen chloride reacted to produce polysilicon at a high temperature of 1100° was relatively high.

Among the materials available at the time, quartz glass was able to meet this parameter requirement and also satisfy corrosion resistance.

That’s why it is quartz glass, that’s why it is 1100°.

Zhang Huiguo completely replicated the first generation improved Siemens method. There were some changes during the process, but they were only minor changes, so this temperature is suitable.

This is the 'why'.

However, scientific research is always seeking its way forward.

Now that you have a way, do you need to find a faster way?
In real life, everyone understands that there is never only one way to reach a destination.

Not to mention the straightening of the original route, if it is possible by land, will it be possible by water?
Even if there is no water route, if the technical conditions are met, there should at least be an air flight method.

The same is true for solving the problem of reduction furnace materials.

When foreigners first made it, there was no such material as 00Cr12Ni10MoTi maraging stainless steel.

This string of stainless steel that looks like garbled numbers and letters has good strength-toughness matching and corrosion resistance, and can be used in aerospace, marine construction, pressure vessel manufacturing and other fields.

At the same time, it is more resistant to high temperatures than ordinary low-carbon stainless steel.

This is the answer to the later stages of the polysilicon reduction furnace under the modified Siemens process.

Obviously, this is not the final answer. The answer of the third-generation ninth edition of Yongxiang Method is a mixture of ultra-low carbon stainless steel, alloys and ceramics.

But this is the best answer that Yun Di can think of under current technical conditions.

Qing Yun exclaimed, pretending to be surprised and said, "When I was reading the progress report of major projects a few days ago, it seemed that Taigang reported a special ultra-low carbon stainless steel.

It is not austenitic stainless steel, but martensitic stainless steel. The name is quite strange, so I paid attention to it.

The safe high temperature resistance coefficient of this stainless steel is 1200 degrees, and the ultra-low carbon stainless steel does not affect the crystal formation at the root.

As for corrosion and radiation resistance...

Mr. Zhang, this material was originally intended to be used in aviation equipment.

Of course, I cannot say what specific aviation equipment will use it, but if it is based on the material coefficients you have told me now, they will definitely meet the requirements.

You can learn more about it and see if it is possible to replace it. After all, this kind of stainless steel is available in our country, and I think the reduction furnace process is not complicated.

I think that once it is usable, it will greatly reduce our construction and production costs.

Of course, this is just a suggestion, the decision is yours.”

Zhang Huiguo's eyes widened when he heard this, and then a look of surprise appeared on his face, "Really? Then this... is really cost-effective!"

In fact, he was a little skeptical.

But after all, he is an old athlete who has experienced several sports games. He is a shrewd man who has survived to this day and knows what expressions and words to show in such occasions.

To be honest, he likes this young man very much, but he is not very satisfied with him being the chairman.
