Great Country Academician

Although the seemingly weird equipment in front of him is producing high-temperature copper-carbon-silver composite superconducting materials, Bruce Walker still stubbornly believes that this may only be a manifestation.

Maybe this Professor Xu just assembled a strange-looking device and produced some substandard superconducting materials?

Testing, that must be done.

Not only because of the ASDEX device transaction, but also because of his inner suspicion.

With the help of an engineer from Western Superconducting Group, Bruce Walker took a section of material from the equipment that was producing superconducting material and put it in a sample bag.

With the help of the product quality testing room of Western Superconducting Group, Bruce Walker began to personally test the parameters of this section of superconducting material.

For a superconducting material, the most important thing is its superconducting performance.

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

The superconducting electromagnetic test system connected to the liquid nitrogen bottle, temperature controller, ammeter and other equipment was turned on, and the addition of liquid nitrogen quickly lowered the temperature of the superconducting material on the measurement and control console.

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

As the temperature dropped little by little, the testing room became quiet, and everyone turned their attention to the display screen connected to the computer and testing 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 falling steadily, will fall to the bottom of the valley like a cliff in the next second.

As everyone has seen in the previous test reports, the 152K high-temperature superconductivity is perfectly reproduced.

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

Although there are still some other items that have not been tested, the critical Tc temperature of 152K is right in front of us. It is basically impossible to expect to find defects or loopholes in other tests.

After all, this is a superconducting material. If other properties change, the critical temperature will definitely change accordingly.

On the side, Claire Bryan asked in surprise: "Mass production is unbelievable. You actually did it. Can you tell me how to do it?"

Xu Chuan smiled and said relaxedly, "It's actually not difficult."

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

"The former is to mix the prepared superconducting powder with high-purity carbon powder with a purity of 99.99% according to a specific ratio, stir and grind them to make them evenly mixed, then press them into shape, and then heat them to a fixed temperature point, and then Then cool down to room temperature at a rate of 1°C/min. to obtain a superconducting bulk material with a plate structure."

"This method is used to manufacture superconducting materials with strange shape requirements. For example, the twisted superconducting coil of the outer layer of your helix 7X can be manufactured in this way."

"As for the chemical deposition method, a thin layer of polymethyl methacrylate PMMA is used as the substrate, and an 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 deposit under special conditions. Just deal with it."

"As for the detailed process and key steps, Western Superconducting Group will arrange engineers and technicians to explain in detail to you when the technology is traded."

After listening to Xu Chuan's introduction, Claire Bryan thought for a while, and said: "But from the electron microscope data of the high-temperature copper-carbon-silver composite material, it has obvious nanostructure rules. How about achieving nanostructures in the fabrication process?"

In fact, after receiving the samples provided by the Chuanhai Institute of Materials Research, it is not that the Planck Institute of Plasma Physics did not try to study it.

After all, if it can be copied, there is no need to trade at all.

The high-temperature copper-carbon-silver composite superconducting material has not applied for a patent. That is to say, as long as they can reproduce it, they can not only use it by themselves, but even apply for a patent in reverse, which can prevent the other party from selling this material internationally. .

It's not impossible.

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

'Compound artemether' is the first drug with a new chemical structure discovered by Hua Guo, and it is also Hua Guo's original drug that has been widely recognized internationally.

As of the end of 2005, it has been designated as the first-line drug for malaria treatment by 26 Asian and African countries, which is a milestone in the history of the treatment of malaria, a highly infectious disease.

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

It is obviously a technology developed by myself, but it has to be controlled by others at the door of my own home. This kind of thing is simply too heartbreaking.

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 has enough confidence in this material. It is very difficult for others to decipher and copy it, and the chance is very small.

And the fact is just as he expected, the Planck Institute of Plasma Physics couldn't replicate it at all, so it had to come to make a deal.

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

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

It is understandable to involve this kind of core, and he just asked curiously, and did not mean to explore the core secrets. However, any material researcher, when faced with such a situation, would probably feel itchy to find out.

The researchers of the Planck Plasma Physics Research spent three days in the workshop of the Western Superconducting Group, and conducted a complete and detailed test on the superconducting materials produced by the small assembly line, and also confirmed the superconducting properties of the copper-carbon-silver superconducting materials. Industrial production.

As for Xu Chuan, he did not accompany him all the time.

His time is precious, and it would be great to be able to accompany him for a trip that day. He left the follow-up matters to other people.

The industrialization of high-temperature copper-carbon-silver composite superconducting materials involves the transaction of the ASDEX device. Not only Chuanhai Materials Research Institute is here, but Qixia Controllable Nuclear Fusion Project has also arranged personnel to assist.

On the high-speed rail, Fan Pengyue and Xu Chuan looked at the distant scenery together. After watching for a while, he suddenly turned his head and sighed: "I have to say, it has to be you. Once you make a move, you will even attack the proud German They all lowered their heads."

"You didn't see the expression of that engineer named Valcke. When he confirmed that the industrially produced materials meet the standards, he looks ugly like eating shit."

"I guess this time I'm afraid I'll be hit hard. After all, you did what they couldn't do."

Xu Chuan smiled, and said: "There are still some differences. Germanic's finishing and automation are indeed very powerful, but in the field of materials, it is not qualified to be the number one in the world."

"That Valcker researcher is just arrogance in his heart. There is no need to pay too much attention to him. I believe there are still some sober people who can see the right side."

"Otherwise, this cooperation will not be negotiated."

To be honest, in some fields, Germany or Europe are indeed at the forefront of the world.

Such as lithography machines, cutting-edge CNC machine tools, optical systems and lenses, semiconductors, etc.

However, many of these technologies actually come from the last century, and are the results of the peak period of Europe in the last century. Now they are just continued to continue to make some optimizations on it.

Since the third industrial revolution, Europe's technology and innovation capabilities have been declining, and now they are almost at the bottom.

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

Today's major breakthroughs in superconducting materials are basically made in the East Asian circle, such as the BI series in Sakura Country, such as the second-generation superconducting materials in Korea.

In Europe, there are basically no breakthroughs in the field of superconducting materials.

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