Chapter 512 Rare Isotope Elements

However, right after Millie said this, she felt uncomfortable and sneezed.

So now, all the nursing trainees who were worried about having no patients to practice on all swarmed to Millie.

Then poor Millie was taken away for treatment without any resistance in front of the group of nursing trainees with shining eyes.

Of course, while the protagonist Kane was doing his mission, Liu Xiu's Wandering Blue Star was researching the transition from micron-level robots to nano-level robots.

Therefore, Liu Xiu naturally invested a lot of research resources in the micro robot research project.

What Liu Xiu didn't expect was that just when Liu Xiu approved the room-temperature superconducting materials needed by the Micro Robot Research Institute, the head of the Resources Department came over and showed Liu Xiu the news that there were not many room-temperature superconductors left.

After reading the report on the use of room-temperature superconductors, Liu Xiu was speechless.

Because there are really not many room-temperature superconductors left that were originally mined from Pandora.

You must know that after Pandora was destroyed by the Zerg, Liu Xiu used the Blackwater virus to directly destroy all the Zerg on the entire Pandora, and then faced a Pandora that had become a ruin and desolate.

Liu Xiu was not polite either and immediately ordered the mining of room-temperature superconductors on Pandora.

However, there are actually not as many room-temperature superconductors on Pandora as imagined. Due to the antimagnetic effect of room-temperature superconductors, the ores of these room-temperature superconductors are basically on the surface of Pandora.

Some high-content room-temperature superconductor ores even floated up directly, and this is also the secret of the formation of the floating mountains on Pandora.

Although it is convenient for mining, the capacity is limited. Of course, for an entire planet, even if it is just on the surface, that is a lot. But it is a pity that Liu Xiu wanted to improve the combat capability of the Wandering Blue Star.

So the order to build a super electromagnetic gun was given later.

In this way, the electromagnetic railgun built after directly penetrating the entire Wandering Blue Planet will naturally require a large number of superconducting acceleration coils.

The material used to build this superconducting acceleration coil is naturally room-temperature superconductor.

So this project alone consumed 90 percent of the superconducting materials mined from Pandora.

Although only 10% is left, the number is still huge. But don’t forget that in addition to superconducting materials, the construction of planet-level electromagnetic cannons also requires them.

Superconducting materials are also needed to build space fighters and space carriers.

After all, space fighters built with room-temperature superconductors can reduce the size of nuclear fusion reactors and annihilation reactors to a very small size.

Of course, it is not impossible to build a nuclear fusion reactor using low-temperature superconductors.

For example, planetary engines are built with low-temperature superconductors. Of course, we have also seen the results, in order to enable low-temperature superconductors to reach the low-temperature environment required for superconductivity.

The cryogenic cooling system of each planetary engine is enormous.

It is precisely because of the huge cooling system that the planetary engine can be built so huge.

Of course, it doesn’t matter if the planetary engine is so bulky and huge, since they are all wandering on the blue planet and no one despises anyone else. However, such a huge cooling system will not work if it is placed on a space fighter that has strict requirements on size and quality.

After all, what space fighters pursue most is flexibility and speed, so there are naturally strict requirements for the nuclear reactors and annihilation reactors that provide energy.

It is precisely because the manufacture of space fighters and space carriers requires a lot of room-temperature superconducting materials, so even if all the superconducting ores on Pandora are mined, it is still not enough. So Liu Xiu had no choice but to issue a restriction on the use of room-temperature superconducting materials.

For example, ordinary transport spacecraft cannot use room-temperature superconducting materials to manufacture reactors.

Instead, they began to choose to use low-temperature superconducting materials, and then added a huge cooling system. Anyway, the transport spacecraft does not care about maneuverability, so it doesn’t matter if it is bigger!

After all, today's technology is vastly different from that of the past. Back then, flying to Mars required the use of chemical-fuel rockets, but nowadays, propulsion is powered by the plasma produced by nuclear fusion.

If the speed is further increased, the annihilation reactor will be used to increase the speed of the plasma, thereby generating greater driving force.

However, since we have obtained space jumping technology from the Space Alliance, we don't need to go too fast. In fact, going too fast is not a good thing.

Of course, space fighters are different and require maneuverability and flexibility, so it is normal to add an annihilation reactor to increase speed.

Of course, Wandering Blue Star has also tried to find the room-temperature superconductors that exist on Pandora.

But the final result was the discovery of room-temperature superconductors on the planet Pandora, which are rare in the universe. For example, ordinary spacecraft in the Cosmic Alliance still use low-temperature superconductors, not room-temperature superconductor nuclear reactors.

However, research and testing on the room-temperature superconductor produced on Pandora found that the superconducting material was actually silver.

Of course, this silver is not the silver produced on the Wandering Blue Star, but a special kind of silver.

In other words, this silver is actually an isotope of silver.

Rather than some kind of alloy. After all, if it is some kind of alloy, there is still a way to replicate it. After all, if it is some kind of alloy of silver, as long as you know the ratio, you can use smelting to achieve the effect and replicate it.

But if it is an isotope, it is different. It can only be obtained through nuclear reaction.

For example, gold is the product of a supernova explosion. Basically, any object below iron is the product of a supernova explosion.

This is like the famous uranium 235 used to make nuclear weapons. So far, this thing is the only material discovered in nature that can undergo nuclear fission.

You have to know that even at this point, if you want to make a large-yield nuclear bomb, you still need uranium 235 to act as a fuse.

Fortunately, since we have learned to produce antimatter hydrogen on a large scale, today's large-yield bombs no longer use nuclear energy as the explosion energy, but instead use antimatter energy as the material.

As we all know, any isotope is naturally very rare. For example, the content of uranium 235 in uranium ore is only a pitiful 0.7%.

If you want to obtain one kilogram of uranium 235 that can be used as a weapon, you have to refine nearly two hundred tons of uranium ore.

Moreover, the refining process is time-consuming and laborious. That is why all the countries that were able to possess nuclear energy at that time had to have a certain industrial capacity.

As for what isotopes are, the definition is also very simple. That is, if two atoms have the same number of protons but different numbers of neutrons, they still have the same atomic number and are elements in the same position in the periodic table, so they are called isotopes.

Of course, radioactive isotopes are called "radioactive isotopes", and those that are not radioactive and have a half-life greater than ten years are called "stable isotopes". Not all isotopes are radioactive.

Uranium 235 is naturally a radioactive isotope.
