Sadao Hirano and Motohisa Nakagawa left like treasures with a small sample of dysprosium terbium ferroalloy given to them by Sun Yuzhi, and they will return to Japan on one of the earliest flights to conduct the most comprehensive examination of the sample to assess the value of the new permanent magnet material.

Sun Yuzhi sent Sadao Hirano and his entourage out of the Beijing office of Daqin Group, watched them get into a taxi and leave, and then returned to the building and came to Qin Hai's office. Qin Hai beckoned Sun Yuzhi to sit down on the sofa, looked at him with a worried look, and asked with a smile, "What, Old Sun, haven't you figured it out yet?" ”

"Taking the patent of dysprosium terbium ferroalloy for the patent of NdFeB, is this transaction a bit of a loss?" Sun Yuzhi asked.

Qin Haidao: "Although dysprosium terbium ferroalloy has better properties than NdFeB in all aspects, the price is too high is its biggest problem, which determines that it will be a piece of chicken ribs in the future." The market for NdFeB will be further expanded, and it is a big piece of fat. What's not worth it to exchange a piece of chicken ribs for a piece of fat? ”

"I'm engaged in scientific research, and I don't know much about the market. Mr. Qin, do you really believe that dysprosium terbium ferroalloy will be too expensive to promote? Sun Yuzhi asked sneeringly.

The research idea of dysprosium terbium ferroalloy was first provided to Sun Yuzhi by Qin Hai. Based on Sun Yuzhi's initial idea, he also felt that the price of dysprosium and terbium was too high, and the market prospect of the new material was not good. But at that time, Qin Hai actively encouraged him to conduct research, and said that as long as the research was done, it would definitely be useful.

Sun Yuzhi mixed dysprosium iron boron and terbium-iron-boron with different formulations, and unexpectedly found that the mixed sinter had a high magnetic energy product and Curie temperature, which far exceeded the performance of NdFeB. But just when he was jubilant and went to rejoice with Qin Poster, Qin Hai said that what he had made was just chicken ribs, and it was better to exchange it with Chunshan Company for the patent of NdFeB.

Qin Hai's practice of turning his hands into clouds and covering his hands into rain made Sun Yuzhi really incomprehensible. But. He is the boss and he is just an employee, since the boss has decided so, what else can he say? He vaguely felt that Qin Hai must have something to say that he hadn't said, and this was not something he should inquire about.

Qin Hai did have something to hide from Sun Yuzhi. It's not because I don't believe in Sun Yuzhi's loyalty, it's just that I'm worried that this nerd will inadvertently leak his mouth and leak the secret of heaven. Qin Hai's plan was to lead Chunshan Company to the evil road of dysprosium and terbium ferroalloy, and then use the rare earth monopoly he had just obtained to increase the price of dysprosium and terbium by ten times, so that dysprosium and terbium ferroalloy would become a luxury item that no one could afford.

In addition to the sharp weapon of rare earth management rights, Qin Hai also has another trump card in his hands. That is another cheaper research idea for new rare earth permanent magnet materials. After Chunshan has gone far enough on the road of dysprosium terbium ferroalloy, if this new material can be introduced, it will ruin Chunshan's efforts.

"Lao Sun, don't worry, the group won't do things that you are not sure about." Qin Hai said, "By the way, from now on, you will hand over the research of dysprosium terbium ferroalloy to the students. I have another idea for my research. I'd like you to give it a try. ”

"What's the idea?" Sun Yuzhi asked curiously.

Qin Haidao: "Think about it, in the periodic table. Next to boron are silicon and carbon, and a little further afield, nitrogen and phosphorus, all of which have similar properties. If boron is replaced with these elements, and neodymium is replaced with adjacent praseodymium, cerium and lanthanum, can one or more new permanent magnet materials be produced? In particular, cerium is used to replace neodymium to form a cerium-based rare earth material with strong magnetic properties. ”

"Use cerium instead of neodymium. Carbon or nitrogen instead of boron? Sun Yuzhi stared at him, looking a little incredulous, "This idea is very novel." If you think about it, the synthesis of carbides is a bit difficult, and what about nitrides. How to solve this problem if the stability is not enough, and it is easy to escape in the sintering process? ”

"Old Sun, this kind of question shouldn't come from your mouth, right?" Qin Hai said with a smile, "You are confused, there is always a way to solve the process problem." In the worst case, the sintering process is not good, and the bonding process is not good? ”

Sun Yuzhi also laughed embarrassedly, he is also concerned about chaos, in fact, there is really no need to worry too much about process problems, there are always more ways than difficulties. He patted his head and said, "It's really confused, it's really confused." However, Mr. Qin, your idea is indeed very interesting, if it can really succeed and replace neodymium with cerium, the price of permanent magnet materials can drop by seven or eight percent at once, which is an epoch-making invention...... By the way, in this way, dysprosium terbium ferroalloy has really become a chicken rib! ”

When he said the last sentence, he suddenly had a sudden sense of realization. The biggest problem with dysprosium-terbium ferroalloy is that it is expensive, and from the perspective of cost performance, it is still less than NdFeB. If one day, I can invent cerium-based permanent magnet materials that are cheaper than NdFeB, then dysprosium-terbium iron alloy is even less valuable. No wonder Qin Hai was so generous and willing to exchange dysprosium terbium ferroalloy with Chunshan Company, it turned out that he had such an idea.

Thinking of this, Sun Yuzhi faintly felt that perhaps Qin Hai already had a very mature idea of what he himself said about cerium-based rare earth permanent magnet materials, otherwise he would not dare to lay out such a big game and wait for the Japanese to jump in. Qin Hai's past actions have proved that he has an unusually accurate intuition in materials research, so his intuition should not be disappointed this time, right?

"This is just one of my assumptions, whether it can be achieved or not depends on your research." Qin Hai naturally would not reveal where his foresight came from, he said: "Once Chunshan Company is willing to take out the patent of NdFeB and exchange it with us, the group will immediately enter the NdFeB industry, and I will take out 30% of the profits obtained to support the research and development of new cerium-based materials." You just let it go, money is not an issue. ”

"Haha, okay, with Mr. Qin's words, I will bring you the new materials no matter what." Sun Yuzhi's spirits were greatly lifted, and he patted his chest and assured Qin Hai.

Regarding scientific research, what Qin Hai can do now is to provide some enlightenment as much as he can, and then give strong support in terms of people, finance, and materials. At present, the School of Materials has formed a good set of scientific research mechanisms, both scientific research services and incentives, which are very mature, and have reached Qin Hai's original expectations.

The material science and technology exhibition was held for a week, attracting the attention of a wide range of people from central leaders to ordinary primary and secondary school students. A large number of Chinese and foreign media have reported on various tidbits at the material exhibition, from magical new materials to various ingenious experience games. The popularization of science on materials science has also taken the opportunity to set off a boom, and a group of materials scientists, including Chen Heqian, have received letters of invitation from several publishing houses.

Dozens of new material patents invented by Anhe Institute of Materials found buyers at the exhibition, although the sales revenue is only more than 10 million yuan, but for the scholars of the School of Materials, it is already a joyful harvest. They were finally able to prove that they were not eating for nothing, but that they could generate profits for the School of Materials. According to the incentive policy of the Institute of Materials, the inventor of the patent can get a part of the patent sales revenue as a reward, and in just a few days, the college has added six or seven "100,000 millionaires", as for the "10,000 yuan household" and the like, no one will pay attention.

The hot sales of various patents of Anhe Institute of Materials have also produced a demonstration effect on other universities and research institutes in China, and some leaders with more flexible brains have begun to put forward slogans such as "patent school" and "application first", forming an atmosphere of combining theory and practice in various units.

The biggest achievement of the materials science and technology exhibition is that the central leaders and a large number of ministry officials have realized the status of materials in modern industry. A few days after the end of the materials exhibition, the State Development Planning Commission submitted to the central authorities a plan for a new round of action to tackle key problems in complete sets of equipment, in which it was clearly stated that tackling key problems in materials and processes should be regarded as the key task, and that the previous mode of thinking of emphasizing products and ignoring materials and processes should be abandoned. This plan has been affirmed by the central leadership, and several leaders have made instructions on the plan, pointing out that attention should be paid to the development of new materials and new processes. These leaders' instructions became the sword of Shang Fang in the hands of the Planning Commission, and they were quickly transmitted to the hands of all key enterprises involved in tackling key problems.

The Heavy Equipment Office carried out another bidding, this time, the plan reported from the enterprises has changed significantly, and the material and process problems that have been plaguing the development of the equipment manufacturing industry have been mentioned in an important position. In fact, the leaders and technicians of various enterprises are veterans who have worked in the industrial field for many years, and they do not know what is most important. In the past, they were only guided by the baton from their superiors, and they did not dare or want to put too much energy into materials, but now they have formed a consensus from top to bottom, and they naturally put their work focus in the right position.

Qin Hai, Chen Heqian, Li Linguang and other material experts have become busier. For the material research projects declared by the enterprise, they should not only review, but also discuss with the enterprise, make suggestions for the enterprise, and help them find a channel to solve the problem. There are many problems faced by enterprises that have certain commonalities, and Qin Hai has facilitated them to establish a cooperative relationship and jointly tackle key problems.

After more than two months of busy work, all the work can be regarded as coming to an end, just waiting for the melons to ripen and harvest fruitful scientific research results. Qin Hai handed over the work of the Heavy Equipment Office to Wang Hongsheng, and then took Chen Heqian, Li Linguang, Yue Kun and others, accompanied by a naval officer, to the 33rd Institute of the Navy. (To be continued......)

PS: Science and engineering students can go to the periodic table, carbon and nitrogen are really close to boron, and the idea of replacing boron with nitrogen is feasible...... Well, that's what we are talking about now as the fourth-generation rare earth permanent magnet material
