Although the strange-looking device is producing high-temperature copper-carbon-silver composite superconducting materials, Bruce Valker still stubbornly believes that this may just be a performance.

Maybe this Professor Xu casually assembled a strange-looking device and produced some superconducting materials of poor quality?

Detection, that's definitely what to do.

Not just because of the trading of the ASDEX device, but also because of the doubts in his heart.

With the help of an engineer from the Western Superconductor Group, Bruce Valker removed a piece of the material from the equipment where it was producing the superconducting material and placed it in a sample bag.

With the help of the Western Superconductor Group's product quality testing room, Bruce Valker began to test the parameters of the superconducting material himself.

For a superconducting material, nothing is more important than superconductivity.

He didn't even do the most basic tunnel scanning electron microscope data collection, and he himself sent the materials he collected back to the measuring equipment.

The superconducting electromagnetic test system connected to liquid nitrogen bottles, temperature controllers, ammeters and other equipment is turned on, and the addition of liquid nitrogen quickly reduces the temperature of superconducting materials on the measurement and control console.

In the blink of an eye, the temperature of the material has dropped below freezing.

As the temperature decreased, the test room fell silent and all eyes were on the display screen that connected the computer to the test system.

When the temperature is close to the transition temperature, when the temperature control system shows that the temperature reaches 152K, the resistance curve, which was originally a steady decline, falls to the bottom like a cliff in the next second.

As everyone has seen in previous test reports, the 152K high-temperature superconductivity is a perfect replica.

Even if he didn't want to believe it anymore, after seeing the bottoming resistance data, Bruce Valker had to believe that Huaguo was really ahead in the field of high-temperature superconducting materials.

Although there are a few other items that have not been tested, the critical Tc temperature of 152K is just around the corner, and it is basically impossible to expect to find flaws or vulnerabilities in other tests.

After all, this is a superconducting material, and if other properties are changed, then the critical temperature will definitely change as well.

On the side, Claire Bryan asked in surprise: "Mass production is incredible, you really did it, can you tell me how to do it?" ”

Xu Chuan smiled and said lightly: "This is actually not difficult. ”

"There are two industrial preparation methods, one is high-temperature sintering pressing, and the other is through vapor deposition."

"The former is to mix the prepared superconducting powder with a purity of 99.99% high-purity carbon powder in a specific proportion, stir and grind, mix it evenly, press it into shape, and then heat it to a fixed temperature point, and then cool it down to room temperature at a rate of 1 °C/min to obtain a superconducting block with plate structure."

"This method is used to make superconducting materials with strange shape requirements, such as your spiral stone 7X's twisted outer layer of strong magnetic superconducting coils, which can be fabricated in this way."

"As for the chemical deposition method, it is through a thin layer of polymethyl methacrylate PMMA as the substrate, and the inert gas that does not react with the superconducting material is used as a protection to clean the superconducting material and the substrate, and then the deposition treatment can be carried out under special conditions."

"As for the specific and detailed process and key steps, when it is time to trade technology, Western Superconductor Group will arrange engineers and technicians to give detailed explanations with you."

After listening to Xu Chuan's introduction, Claire Bryan thought for a while and said: "But judging from the electron microscopy data of high-temperature copper-carbon-silver composite materials, it has obvious nanostructure laws, how can you ensure that the nanostructure of the material is realized in the manufacturing process with these two methods?" ”

In fact, after getting the samples provided by the Chuanhai Materials Research Institute, the Planck Institute for Plasma Physics did not find a way to study it.

After all, if you can copy it, there is no need to trade at all.

High-temperature copper-carbon-silver composite superconducting materials are not patented, that is, as long as they can reproduce them, they can not only use them themselves, but they can even apply for a patent in reverse, and they can prohibit the other party from selling this material internationally.

It's not impossible.

In the early years, 'coartemether' was a good example.

'Compound artemether' is the first drug with a new chemical structure discovered by China, and it is also an original drug in China that has been widely recognized in the world.

By the end of 2005, it had been designated as a first-line drug for the treatment of malaria in 26 Asian and African countries, and it was a milestone in the history of the treatment of malaria, a highly contagious disease.

However, because the patent was taken away by the Swiss company Novartis, the compound artemether produced in China could not pass the certification of the international WTO and could not be exported.

It's obviously a technology developed by himself, but he has to be controlled by others at his own doorstep, this kind of thing is simply heart-wrenching.

However, this kind of thing is unlikely to happen in Xu Chuan's hands.

The high-temperature copper-carbon-silver composite material did not apply for a patent because he had enough confidence in this material, and it was very difficult and very unlikely for others to decipher and copy it.

And just as he expected, the Planck Institute for Plasma Physics couldn't replicate it, so he had to come and make a deal.

Hearing this question, Xu Chuan said with a smile: "It is a catalyst that can automatically optimize the crystal structure of copper-carbon-silver composites, but this is the core of synthetic superconducting materials, if you want to know, you need to wait until the contract is signed." ”

Claire Bryan shrugged her shoulders and said with a little disappointment, "Okay." ”

It is understandable that this kind of core is involved, and he only asks curiously, and does not mean to explore the core secrets. However, any materials researcher, when faced with this situation, will probably be itching to explore the end.

Planck plasma physics researchers spent three days in the plant of the Western Superconductor Group, conducted a complete and detailed test of the superconducting materials produced by the small assembly line, and also confirmed the industrial production of copper-carbon-silver superconducting materials.

As for Xu Chuan, he didn't accompany him all the time.

His time is precious, and it is already good to be able to accompany him on a trip that day, and he leaves the rest to others.

The industrialization of high-temperature copper-carbon-silver composite superconducting materials involves the transaction of ASDEX devices, and not only the Chuanhai Materials Research Institute has come here, but also the Qixia Controlled Nuclear Fusion Project has also arranged personnel to assist.

On the high-speed train, Fan Pengyue and Xu Chuan looked at the scenery in the distance, and after looking at it for a while, he suddenly turned his head and sighed: "I have to say, it has to be you." As soon as you make a move, even the proud Germanic Yakee bow their heads. ”

"You don't see the expression of the engineer named Valker, when it is confirmed that the industrially produced materials meet the standards, it looks like eating."

"I guess I'm afraid I'm going to be hit hard this time, after all, what they can't do, you did it."

Xu Chuan smiled and said: "There are still some differences, the finishing and automation on the Germanic side are indeed very powerful, but in the field of materials, it is not qualified to say that it is the first in the world." ”

"That Valk researcher is just arrogant inside, so there's no need to pay too much attention to him. I believe that there are still some sober people who can see the right aspects. ”

"Otherwise, this cooperation will not be negotiated."

To be honest, in some areas, Germania or Europe is indeed at the forefront of the world.

For example, lithography machines, cutting-edge CNC machines, optical systems and lenses, semiconductors, and so on.

However, many of these technologies actually come from the last century, and they are the results of the peak of Europe in the last century, and now they are just continuing to make some optimizations on them.

Since the Third Industrial Revolution, Europe's technological and innovation capabilities have been declining, and now they are almost at rock bottom.

And in the field of materials, especially in the field of superconducting materials, they are even less qualified to look down on others.

Nowadays, major breakthroughs in superconducting materials are basically made in East Asia, such as the BI series in Sakura Country, such as the second-generation superconducting materials in Korea.

In Europe, there is basically no breakthrough in the field of superconducting materials.

If there is, even if it is a second-class high-temperature superconducting material, they will not choose to buy it.
