After arriving in the capital, Wang Hao went straight to the Aviation Materials Institute.
Because they had not said hello in advance, the Aviation Materials Institute was not prepared for this. Cao Dongming, who knew the news, went to call the servants, which made the greeting team at the door seem more lively.
Qu Shigang and Ai Yongchuan, two old academicians, came over.
They also complained about Cao Dongming and said, "Academician Wang Hao is coming. Why didn't you tell me about such a big thing earlier?"
"That's right, if you know how to hang up a banner, just a dozen people like this..."
Ai Yongchuan looked around and said with some worry, "Don't let Academician Wang Hao think that our hospitality is not good enough!"
"I just found out too."
Cao Dongming smiled bitterly and said, "Academician Wang came by car. He said he slept in the car that night and didn't bother me because it was too late. He just called and said he had arrived in the capital and was coming over."
"It's like a surprise inspection." Qu Shigang said depressedly, and then asked, "This time Academician Wang is here..."
"Our research, Qu Gui and I!"
Cao Dongming said with some pride, and continued, "Academician Wang said that our discovery was very important, so he decided to come and take a look."
"Cooperation with Academician Wang?"
"right."
Qu Shigang gave a thumbs up to Cao Dongming.
Ai Yongchuan joked, "It must be a big achievement to have Academician Wang travel a long way here. Dongming, you just won the third prize in science and technology. Do you plan to keep up your efforts and win the second prize this year?"
Everyone next to me laughed.
Cao Dongming also laughed twice, knowing that Ai Yongchuan was joking. How can it be so easy to win the Science and Technology Progress Award?
While a few people were chatting and joking, they heard a voice in the distance shouting, "Here we come."
They immediately moved forward to meet him.
A military vehicle drove over and stopped in the open space at the door. A guard with a gun came down from the co-pilot and helped open the side door.
Wang Hao got out of the car.
Qu Shigang, Cao Dongming and others immediately came over to greet them. Not only did they shake hands and exchange pleasantries, Ai Yongchuan kept saying polite words such as "not well received".
Of course Wang Hao didn't mind the poor reception. He directly mentioned the purpose of coming, "I came here this time for the research of Professor Cao and Professor Qu."
He suddenly thought of something and said with a smile, "By the way, I should call you Academician Cao."
Everyone else laughed.
Last year, Cao Dongming won the Scientific Progress Award and was elected as an academician of the Academy of Engineering. His personal achievements have been greatly improved.
Cao Dongming said a few polite words, and then talked about the research findings with Wang Hao.
Cao Dongming simply said before that he only knew that the research was to discover a method of separating first-order iron, but he did not expect that Wang Hao would make a special trip to the Aerospace Materials Institute.
Wang Hao's arrival in the capital was a big event.
It is no longer a few years ago. It is not easy to see Wang Hao. Even some high-level leaders go to Xihai specifically to see Wang Hao.
So when they knew Wang Hao was coming to the capital, some leaders sent people over in advance to wait.
As long as Wang Hao has finished his own business, he can quickly pull him over to talk about other things. Wang Hao doesn't have much time to stay in the Aeronautical Materials Institute.
Cao Dongming knew that Wang Hao had a tight schedule, so he simply took Wang Hao to the laboratory.
At this time, irrelevant people can only leave.
All projects of the Institute of Aeronautical Materials are confidential to a certain extent, not to mention the projects jointly researched with Wang Hao. Because of this, even Qu Shigang did not inquire specifically about the research content.
In the laboratory, Wang Hao met Qu Gui.
The main people in charge of this research are Cao Dongming and Qu Gui. Qu Gui is an outstanding talent recommended by Cao Dongming. He is only forty years old and has only an undergraduate degree. He received his graduate degree on the job. He started from the lowest level as an assistant technician.
I quickly rose up the ranks step by step, and am now a researcher.
With a bachelor's degree, it is not easy to successfully stay in the Institute of Aeronautical Materials. If you study on the job as a graduate student and work as a researcher at the age of 40, you are naturally quite capable.
“It was also Professor Qu’s idea to conduct experiments with magnetized iron materials.”
Cao Dongming had no intention of taking any credit. He obviously admired Qu Gui very much. "At that time, Professor Qu said he would try using magnetized iron materials. I thought it was too extravagant."
He immediately smiled bitterly and said, "This is not a matter of funding. Even in our hospital, if you want to use magnetized iron materials, you have to apply. It's just magnetized materials, not extracted first-order iron."
Wang Hao nodded lightly.
The price of first-order iron is very high, but magnetized iron materials are much cheaper.
Now in the international market, the selling price of first-order iron materials is US$800,000 to US$1 million per kilogram.
Magnetized iron materials are relatively expensive, but the main reason is that Annihilation Technology Company's manufacturing capacity is limited, and part of it must be used for external sales to achieve high profits, so the supply of materials to the domestic technology sector is also limited.
After discussing their ideas, Cao Dongming and Qu Gui introduced the experiment together, "Our furnace temperature is maintained between 1560 and 1600 degrees Celsius, and a special environment of high magnetism and high pressure is created."
"In this environment, we stirred in all directions and conducted experimental observations."
"Initially, we didn't find anything, but after the experimental material cooled and solidified, we tested it again and found that the content of first-order iron increased a lot in the edge part of the material, while it dropped significantly in the center part."
"Later, we conducted experiments and determined that unidirectional stirring will cause the first-order iron in the magnetized material to gather toward the edge..."
Wang Hao listened to the explanations of the two men and looked at the experimental report in his hand.
This is not a large experiment.
The 'magnetized iron material' Cao Dongming mentioned is only a small piece, and the furnace is also used in laboratories. It is very easy to create high-temperature, high-magnetic and even high-voltage environments.
Wang Hao put down the report in his hand, picked up a piece of solidified magnetized iron material, and observed it carefully. Of course, he found nothing.
He is thinking about a question--
Why does unidirectional stirring in high magnetic, high pressure and high temperature environments cause first-order iron to gather toward the edge?
What principles are contained in it?
In an environment of 1550 to 1600 degrees Celsius, conventional iron will melt at high temperature, while the melting point of first-order iron is higher and remains in a solid state.
But this is just theory.
The first-order iron in the magnetized iron material is absolutely uniformly distributed. The so-called "absolutely uniform" is compared with microscopic atoms, and the overall content is only a little more than 2%.
When the melting point of conventional iron is reached, it is impossible to separate the first-order iron using only physical means of stirring. In other words, the high magnetic and high pressure environment plays a role.
“It still comes down to specificity.”
"Under a strong annihilation force field, the magnetic field emitted by first-order iron elements is different, so the effects of the magnetic field will definitely be different..."
Wang Hao thought and pressed his forehead hard.
Although this is indeed the case in theoretical analysis, experimental studies have found nothing, and it is impossible to distinguish between iron elements and first-order iron elements using only magnetic fields.
"Also, high voltage..."
"Elementary iron, with its simple internal semi-topological structure, cannot explain anything."
"If it were an iron-based superconducting material, there would be no difference between first-order iron and conventional iron after melting, and similar discoveries would not be possible."
"So, how to make the effect of semi-topological structure manifest?"
Wang Hao thought of microsphere manufacturing.
To make microspheres, melted materials are placed in a specific solution and continuously stirred during the cooling and solidification process, so that the material can be separated into small balls.
"Is it okay to replace it with iron-based superconducting material and put it in the melted liquid of a superconducting material with a higher melting point?" His eyes suddenly lit up.
This idea has been around for a long time, but there has never been a clear idea.
Now Cao Dongming and Qu Gui's experimental discoveries have made him more clear about his research and development ideas, and at the same time, he also thought of many technical problems that must be overcome--
For the semi-topology to work, high-voltage energization must be maintained during the manufacturing process.
For superconducting materials with higher melting points, it is not easy to find suitable ones.
In addition, the problem of high magnetism also needs to be solved.
But no matter how many technical problems there are to overcome, the most important thing is to clarify the research direction. Wang Hao immediately explained, "Academician Cao, Professor Qu, please make a detailed report as soon as possible."
"This achievement of yours is very remarkable. It is very important to my research and to the manufacturing technology related to first-order iron."
Cao Dongming asked doubtfully, "Isn't the manufacturing technology of first-order iron...not extraction?"
To be continued...
