Great Country Academician

Capital city, science and technology center.

In the Institute of Materials Technology and Engineering of the Chinese Academy of Sciences, a certain laboratory is working overtime to test a material.

Even though it was already late at night, many people were still waiting for the result.

"Chief Qin, the test results have come out."

In the laboratory, a middle-aged man in a white coat walked in with a test report in his hand.

"what's the result?"

Qin Anguo, who had been waiting in the laboratory for a long time, couldn't wait to ask quickly.

"The critical temperature is 152K, and the critical magnetic field can reach 25T." The middle-aged man in a white coat replied with a hint of disbelief on his face: "I'm curious, where did you get this material? I haven't heard of it." Which research institute or laboratory has made such a major breakthrough in high-temperature superconducting materials."

Qin Anguo quickly asked: "Is this data excellent?"

He is not an expert in the material field. Although he knows some information about superconducting materials, he does not understand the specific parameters in detail.

Academician Zhang Pingxiang nodded and said: "It's not just excellent, this parameter can be said to break the current record of high-temperature superconductivity."

"Currently the best materials in the field of high-temperature superconducting materials can only achieve a critical temperature of about 120K, and those that can break through double digits in terms of critical magnetic field are already excellent."

"Just like the latest Bi2Sr2Ca2Cu3O10 superconducting material (Bi-2223 for short) high-temperature superconducting material previously developed by Sakura Country, the current critical transition temperature is almost 108-110 K, which is a difference of more than 40K. The critical magnetic field is 16.8T, and There’s a big difference between this and that.”

After a pause, Academician Zhang Pingxiang then asked: "By the way, where did you get this material? I haven't heard of any laboratory or research institute at home and abroad that studies the superconductivity of copper-carbon-silver composite materials." ?”

Qin Anguo: "So this material is quite important?"

Zhang Pingxiang nodded without hesitation, "Of course it's very important."

"At present, superconducting materials in the world, referring to commercialization, are still dominated by ultra-low temperature superconducting materials such as NbTi and Nb3Sn that need to be frozen with liquid helium."

"Although the comprehensive performance of commercial low-temperature superconducting materials is constantly improving through in-depth research on the relevant mechanisms of existing preparation technologies. However, the limitations of ultra-low temperature superconducting materials are undoubtedly very large, such as the need for liquid helium cooling, and the current price of liquid helium Quite expensive."

"But high-temperature superconducting materials are different. The technology for preparing liquid nitrogen is quite mature, and the price is quite cheap. If high-temperature superconducting materials can be commercialized, the use of superconducting materials will be more extensive and popular."

"It's just that in the field of high-temperature superconducting materials, there are only a few that can be commercialized. Among them, Bi-2223 strips and REBCO coated conductors are representatives. At present, only Sumitomo Electric Industries Co., Ltd. in Sakura Country a supplier."

"As for China, although the research on high-temperature superconducting materials is quite deep, and there are many types of high-temperature superconducting substrates, none of them can be commercialized at present, and can only be produced in small batches in laboratories. "

Qin Anguo thought for a while and said, "In other words, if it can be produced industrially, this material will directly monopolize the entire high-temperature superconducting material market?"

Zhang Pingxiang nodded and said: "It can be said that even the Bi-2223 tape from Sakura Country is helpless in the face of this superconducting material."

After thinking about it, Qin Anguo then asked: "Then can this kind of material be applied to controllable nuclear fusion projects or large-scale strong particle colliders?"

Zhang Pingxiang: "According to the current test data, there is no problem."

After a pause, he thought for a while and then continued: "Even to a certain extent, it can be applied to electromagnetic weapons or particle weapons, because its critical magnetic field and critical current density are extremely large, and it can be used within a short distance. Provides an extremely high magnetic field."

"If you want to talk about the disadvantages, it is that the physical properties of this material are brittle. It is more like a ceramic series material, and the shock resistance may not be very high."

"Of course, we didn't test the specific physical properties, because there are only two small pieces of material, and we need to study them later."

Hearing this, Qin Anguo's pupils shrank violently, and his breathing became heavy: "What you said is true?"

Zhang Pingxiang nodded and said: "Of course, in this kind of matter, we must use data to speak."

Swallowing the air dryly, Qin Anguo thought for a while, and said, "Well, let me see a copy of the data, and then make a judgment for me."

When the great elder gave him the high-temperature copper-carbon-silver composite superconducting material and related test data, he only provided the raw materials to the Chinese Academy of Sciences, and kept the test data for comparison.

Now it seems that it may be necessary to make a judgment based on the test data first.

If it can really be used in electromagnetic physics or particle beam weapons, then he has to go to Jinling immediately to communicate with that person about how to deal with this material.

Hearing this, Academician Zhang Pingxiang became a little curious.

Originally, he thought that this material should come from abroad, and it might have been obtained through some means. This is not something to be surprised about. He has also helped the country analyze a lot of "accidental" materials before.

But now it seems that the materials he analyzed in the past two days may come from a certain laboratory or research institute in China?

After all, people are old and smart, and when Qin Anguo said to take him to look at the data, he can probably think about something clearly.

It's just that he was even more curious.

Which laboratory or research institute in China has such top-level research and development capabilities that can develop high-temperature superconducting materials to this point, and it is not a conventional copper oxide-based material?

Following Qin Anguo, the two came to another office.

Qin Anguo opened the notebook he carried with him, and clicked on the detailed test data of the high-temperature copper-carbon-silver composite superconducting material.

"This is the detailed data of that material. I would like to ask Academician Zhang to help me see if the data can meet the standards you mentioned before. If there are any deficiencies, please let me know."

Hearing this, Zhang Pingxiang nodded, and took the notebook from Qin Anguo out of curiosity.

"How is it? Can it meet the standard?" After a while, Qin Anguo asked nervously.

Zhang Pingxiang: "From the data point of view, theoretically speaking, there should be no problem."

"But the problem I said before is also reflected in this data, that is, this material is biased towards ceramics, with high brittleness, low shock resistance and impact resistance, and is fragile; the post-processing ability is low. If you want to apply it For electromagnetic weapons or particle weapons, this shortcoming can be said to be fatal."

"Is there a solution?" Qin Anguo asked quickly.

"Yes, there are." Zhang Pingxiang thought for a while and replied: "According to the traditional solution, other seismic materials are used to make up for it, just like the cables for ultra-long-distance power transmission. support."

"And this one, too, can be supplemented somewhat with cushioning on the outside."

"But you should be very clear that if it is used in weapons, shock resistance and impact resistance are inevitable."

"So the best way is to optimize the material itself. If it can be optimized, it doesn't even need the degree of stretching of the steel level. It can be tempered film or glass fiber level, even if it is the lowest grade. Cushioning material, should be enough."

"Of course, whether it can be done or not, I need to meet with the research and development personnel of this material and communicate with him."

He knew that Qin Anguo would definitely look for the research and development personnel of this material in the future, so he expressed in his words that he also hoped to be with him, especially after guessing that there was a great possibility that it was produced by a domestic laboratory. I hope to meet this mysterious researcher even more.

He really wants to meet a god-man of this level who can break away from the basis of conventional oxide superconducting materials and open up an excellent new route in other fields.

PS: The computer crashed, and I don’t know if it’s the solid state or the hard drive or something is wrong. Anyway, it crashed and sent it for repair (big head. JPG). After today’s update, I still used my mobile phone to grind it out bit by bit. The efficiency is thieves Low, I will use my mobile phone to grind a chapter at night, and everyone will watch it when they wake up tomorrow morning.

Whisper: I bought Yaoo’s computer when I was working in 2015, and I have used it for eight years. (.ω.)
