Chapter 348: Monopolizing the high-temperature superconducting material market
Beijing, Ministry of Science and Technology.
At 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 late at night, there were still many people waiting for the results.
"Minister 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, asked quickly and impatiently.
"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 materials field. Although he knows some information about superconducting materials, he does not understand the specific parameters in detail.
Academician Zhang Pingxiang nodded and said: "More than excellent, this parameter can be said to have broken the current record of high-temperature superconductivity."
"Currently, the best materials in the field of high-temperature superconducting materials can only reach 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) previously developed by Sakura Country, the current critical transition temperature is almost 108-110 K, a temperature difference of more than 40K, the critical magnetic field is 16.8T, and
Comparing this, there is a big difference.”
After a pause, Academician Zhang Pingxiang then asked: "By the way, where did you get this material? I haven't heard of any laboratories or research institutes at home and abroad that are studying superconductivity in copper-carbon-silver composite materials.
?”
Qin Anguo: "So this material is quite important?"
Zhang Pingxiang nodded without hesitation: "Of course it's important."
"Currently, the superconducting materials in the world, referring to commercialization, are still mainly superconducting materials such as NbTi and Nb3Sn that require ultra-low temperature and need to be frozen with liquid helium."
"Although through in-depth research on the mechanisms related to existing preparation technologies, the comprehensive performance of commercial low-temperature superconducting materials is constantly improving. However, ultra-low-temperature superconducting materials undoubtedly have great limitations, 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 scope of use of superconducting materials will be more extensive and popular."
“At present, only a few types can be commercialized in the field of high-temperature superconducting materials, among which Bi-2223 strips and REBCO coated conductors are representatives. Currently, 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, they are currently not commercialized and can only be produced in small batches in the laboratory.
"
Qin Anguo thought for a while and said: "In other words, if it can be industrialized, 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 strip from Sakura Country has no power to fight back against this superconducting material."
After thinking about it, Qin Anguo then asked: "Can this material be applied to controllable nuclear fusion projects or large strong particle collider or something like that?"
Zhang Pingxiang: "According to the current testing data, there is no problem."
After a pause, he thought for a moment and then continued: "Even to a certain extent, it can be used in electromagnetic weapons or particle weapons, because its critical magnetic field and critical current density are extremely large, and it can achieve
Provides extremely high magnetic field."
"If we want to talk about the shortcomings, it is that the physical properties of this material are relatively brittle. It is more like a ceramic series material, and its earthquake resistance may not be very high."
"Of course, we did not test the specific physical properties, because the material is only two small pieces and needs to be studied later."
Hearing this, Qin Anguo's penis contracted violently, and his breathing became heavier: "Is what you said true?"
Zhang Pingxiang nodded and said: "Of course, data must speak for itself in this kind of matter."
After swallowing dryly, Qin Anguo thought for a moment and said, "In this case, you can come and see some data with me, and then you can make a judgment for me."
When the Great Elder handed over the high-temperature copper-carbon-silver composite superconducting material and related test data to him before, he only provided the raw materials to the Chinese Academy of Sciences and kept the test data for comparison.
Now it seems that we may need to make a judgment based on test data first.
If it could really be used in electromagnetic physics or particle beam weapons, he would have to go to Jinling immediately to communicate with the person about how to process this material.
Hearing this, Academician Zhang Pingxiang became a little curious.
Originally, he thought that this material should come from abroad, possibly obtained through some means. This is not something surprising. He has helped the country analyze a lot of "accidentally" obtained materials before.
But now it seems that the materials he analyzed in the past two days may have come from a certain laboratory or research institute in China?
After all, people become wiser with age, and once Qin Anguo asked him to take him to see the data, he would be able to think about something clearly.
But, he was even more curious.
Is there any domestic laboratory or research institute with such top-level R&D capabilities that can advance high-temperature superconducting materials to this level, 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 testing data of high-temperature copper-carbon-silver composite superconducting materials.
This chapter is not over, please click on the next page to continue reading! "This is the detailed data of that material. Please help Academician Zhang to see if the data can meet the standards you mentioned before. If there are any deficiencies, please let me know
You have to tell me."
Hearing this, Zhang Pingxiang nodded and took the notebook from Qin Anguo with curiosity.
"How is it? Can it meet the standard?" After a while, Qin Anguo asked nervously.
Zhang Pingxiang: "Judging from the data, theoretically there should be no problem."
"But the problem I mentioned before is also reflected in this data, that is, this material tends to be ceramic, has high brittleness, low seismic resistance and impact resistance, and is brittle; 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.
"There are still some." Zhang Pingxiang thought for a while and replied: "According to the traditional solution, it is to use other anti-seismic materials to supplement it, just like ultra-long-distance power transmission cables, which use steel with high tensile strength internally.
support."
"The same goes for this one, which can be supplemented to a certain extent by using cushioning materials on the outside."
"But you should know very well 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 to be stretched at the steel level. It can be tempered film or glass fiber level, even the lowest grade, and then cooperate with it.
Cushioning material should be enough."
"Of course, to see if it can be done specifically, I need to meet with the developer of this material and communicate with him."
He knew that Qin Anguo would definitely find the developers of this material in the future, so he expressed in his words that he also hoped to follow him, especially after he guessed that it was very likely that a certain domestic laboratory had created it.
I even hope to meet this mysterious researcher.
He really wanted to meet a man of this level who could break away from the basics of conventional oxide superconducting materials and open up a new and excellent route in other fields.

PS: My computer crashed, and I don’t know if it’s the solid state, the hard drive, or something else. Anyway, it crashed and was sent to be repaired (big head.JPG). Today’s update was done bit by bit using my mobile phone. It’s very efficient.
Okay, I'll use my phone to grind out a chapter at night, and everyone will read it when they get up tomorrow morning.
Xiaosheng: Yawei bought his computer when he was working in 2015 and has been using it for eight years. (.?w?.)
