Chapter 367: The Germanic guy who lowered his head
Although the strange-looking equipment in front of him is producing high-temperature copper-carbon-silver composite superconducting materials, Bruce Valk still stubbornly believes that this may be just a manifestation.
Maybe Professor Xu randomly assembled a strange-looking piece of equipment and produced some superconducting materials of substandard quality?
Testing is definitely something that needs to be done.
Not only because of the transaction of the ASDEX device, but also because of the doubts in his heart.
With the help of a Western Superconductor Group engineer, Bruce Valk removed a section of material from equipment that was producing superconducting materials and placed it into a sample bag.
With the help of the product quality inspection room of Western Superconducting Group, Bruce Valk began to personally test various parameters of this superconducting material.
For a superconducting material, the most important thing is its superconducting performance.
He did not even do the most basic tunnel scanning electron microscope data collection. He fed the materials collected by himself into the measurement equipment.
The superconducting electromagnetic testing 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 control table.
In the blink of an eye, the temperature of the material has dropped below zero.
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 that was originally declining steadily will fall directly to the bottom like a cliff in the next second.
As everyone has seen in previous test reports, the 152K high-temperature superconductor is perfectly reproduced.
Even if he no longer wanted to believe it, after seeing the bottom-out resistance data, Bruce Valcke had to believe that China was really leading the way in the field of high-temperature superconducting materials.
Although there are 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 are changed, the critical temperature will definitely change accordingly.
On the side, Claire Bryan asked in surprise: "Mass production is incredible. You actually did it. Can you tell me how it was done?"
Xu Chuan smiled and said relaxedly: "This is actually not difficult."
"There are two industrial preparation methods, one is high-temperature sintering and pressing, and the other is through vapor deposition."
"The former is to mix the prepared superconducting powder and high-purity carbon powder with a purity of 99.99% according to a specific ratio, stir and grind them to make them evenly mixed, press them into shape, and then heat them to a fixed temperature point.
Then cool it down to room temperature at a rate of 1°C/min. to obtain a superconducting block with a plate structure."
"This method is used to manufacture superconducting materials with strange shape requirements. For example, the strong magnetic superconducting coil with a twisted outer layer of your Spiralite 7X can be manufactured in this way."
"As for the chemical deposition method, a thin layer of polymethylmethacrylate (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 substrate, and then deposited under special conditions.
Just deal with it.”
"As for the detailed process and key steps, when the technology is traded, Western Superconducting Group will arrange engineers and technicians to explain it in detail to you."
After listening to Xu Chuan's introduction, Claire Bryan thought for a while and said: "But judging from the electron microscope data of high-temperature copper-carbon-silver composite materials, it has obvious nanostructure rules. How about your two methods?
What about ensuring that materials achieve nanostructures during the manufacturing process?”
In fact, after receiving the samples provided by the Sichuan-Hai Institute of Materials, the Planck Institute of Plasma Physics did not think of ways to study them.
After all, if it could be copied, there would be no need to trade at all.
The high-temperature copper-carbon-silver composite superconducting material has not applied for a patent. In other words, as long as they can copy it, they can not only use it themselves, but they can even apply for a reverse patent to prohibit the other party from selling this material internationally.
.
This is not something impossible.
In the early years, ‘complex artemether’ was a good example.
‘Complex artemether’ is the first drug with a new chemical structure discovered by China, and it is also an original Chinese drug that has been widely recognized internationally.
By the end of 2005, it had been designated as a first-line drug for malaria treatment by 26 Asian and African countries. It is 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 international WTO certification and could not be exported.
It is so heartbreaking to think that the technology that was obviously developed by oneself has to be controlled by others at the doorstep of one's own home.
However, this kind of thing is unlikely to happen in Xu Chuan's hands.
The reason why he did not apply for a patent for the high-temperature copper-carbon-silver composite material is 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 was just as he expected, the Planck Institute of Plasma Physics couldn't replicate it at all, so he had to come to trade.
Hearing this question, Xu Chuan said with a smile: "It is a catalyst that 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 slightly disappointedly: "Okay."
It is understandable that this kind of core is involved. He just asked out of curiosity and did not mean to explore the core secrets. However, any materials researcher, when faced with this situation, would probably be itching to explore.
after all.
This chapter is not over, please click on the next page to continue reading!......
Researchers from the Planck Plasma Physics Research spent three days at the Western Superconducting Group's factory, conducting complete and detailed tests on the superconducting materials produced by the small assembly line, and also confirmed the performance of the copper-carbon-silver superconducting materials.
Industrial production.
As for Xu Chuan, he no longer accompanies him all the time.
His time was precious, so it was good to go with him on that day. He left the follow-up matters to others.
The industrialization of high-temperature copper-carbon-silver composite superconducting materials involves the transaction of the ASDEX device. Not only are people from the Sichuan-Hai Materials Research Institute coming, but people from the Qixia Controlled Nuclear Fusion Project are also coming to assist.
On the high-speed train, Fan Pengyue and Xu Chuan looked at the distant scenery together. 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 take action, even the proud Germanic old man
They all lowered their heads."
"You didn't see the expression on that engineer named Valcke's face. When he confirmed that the industrially produced materials met the standards, he looked as ugly as if he had eaten shit."
"I guess I was hit hard this time. After all, you did what they couldn't do."
Xu Chuan smiled and said: "There are still some differences. Germania's finishing and automation are indeed very powerful, but in the field of materials, it has no qualifications to say that it is the best in the world."
"That researcher Valcke is just arrogant 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 correct aspects."
"Otherwise, this cooperation will not be successful."
To be honest, in some areas, Germany or Europe are indeed at the forefront of the world.
For example, photolithography 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 and continued to make some optimizations on them.
Since the third industrial revolution, Europe's technology and innovation capabilities have been declining, and now they have almost reached rock bottom.
In the field of materials, especially 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, and the second-generation superconducting substitute materials in Korea.
In the field of superconducting materials, Europe has basically made no breakthroughs.
If there were, even if it was a sub-level high-temperature superconducting material, they would not choose to outsource it.
