I Am the President of the University

"High-purity silicon nitride powder?"

Not only Chen Hao, but also Chen Chong and Fang Haosen also cheered up.

To mention high-purity silicon nitride powder, we must first mention "advanced ceramics".

In recent years, new materials have been a key research and development direction in my country and many countries, and have been widely used in industry, national defense, aerospace, electronics, biomedicine and other fields. However, compared with developed countries such as Europe, the United States, and Japan, my country's advanced ceramic industry is generally significantly behind the level of developed countries.

What are advanced ceramics?

Advanced ceramics, also known as high-performance ceramics, fine ceramics, high-tech ceramics, etc., refer to the use of high-purity, ultra-fine artificially synthesized or selected inorganic compounds as raw materials, with precise chemical composition, precise manufacturing and processing technology and structure Ceramics designed and have excellent mechanical, acoustic, optical, thermal, electrical, biological and other properties.

According to their characteristics and uses, they can be divided into two categories: structural ceramics and functional ceramics, but functional ceramics account for about 70% of the market share among advanced ceramics.

Compared with other countries, my country started slowly. It was only after entering the 21st century that the research on functional ceramics received the attention of the country and various scientific research institutes.

But the road to catch up is quite difficult.

Take bearings as an example.

Bearings are an extremely important component in mechanical equipment and are widely used.

Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Moreover, the function of bearings is similar to that of human joints, so they are called "mechanical joints" and are also called "chips" in the mechanical industry.

In today's bearing field, silicon nitride ceramic ball bearings have gradually replaced traditional steel ball bearings.

Compared with traditional steel ball bearings, silicon nitride ball bearings have a series of advantages such as light weight, high limit speed, small friction torque, good operating accuracy, and long service life. Their performance in all aspects is balanced, excellent, and comprehensive, and can be called the best in the bearing industry. of "Hexagon Warriors". 1

The raw material of silicon nitride ceramic ball bearings is called silicon nitride powder. The higher the purity of the powder, the higher the product quality.

But what many people don’t know is that it’s not just mobile phone chips that are stuck in China. Just like the lactide mentioned above, the raw material for degradable straws actually needs to be imported.

Similarly, high-purity silicon nitride powder in my country is still restricted by Japanese UBE Company and German H.C. Stark Company. In particular, Japanese UBE Company strictly limits the supply to the Chinese market, making domestic high-quality silicon nitride ceramic balls Producers are constrained by the supply of raw materials.

Chen Hao and others are naturally aware of these issues, but they are not involved in this area because of their skills.

Unexpectedly, I got a surprise in today's interview.

"Dr. Huang, are you really sure to prepare high-purity silicon nitride powder? This is not a simple subject." Chen Hao asked again with certainty.

If the other party can really do it, it will be great and it can solve the country's raw material supply problem in this field.

Huang Jie understood what Chen Hao meant. At this moment, he didn't panic, but was extremely calm.

"I'm sure!"

"When I was at the National Institute of Materials Science and Technology in Japan, the institute had some cooperation with Japan's UBE company, and I was also involved in it. I know how to prepare high-purity silicon nitride powder from head to toe," Huang Jie said seriously.

Chen Hao and Chen Chong looked at each other, and then the questioner changed to the latter.

"UBE, the core technology of high-purity silicon nitride powder, shouldn't let you see it, right? And if there are patent issues, it will be troublesome."

"UBE certainly wouldn't let me see the core department, but I figured it out later. As for patents, it's not a big problem."

Huang Jie continued to explain: "The synthesis methods of silicon nitride powder mainly include silicon powder nitridation method and chemical synthesis method. Domestic manufacturers almost all use silicon powder nitridation method. Compared with powder prepared by chemical synthesis method, The powder prepared by the latter has high purity, good sphericity, high sintering activity, and is less affected by the stability of silicon raw materials. Japan's UBE Company is also the only company that can use this method to produce silicon nitride powder."

"But I think there is another synthesis method that is more pure than the silicon nitride powder prepared by Japan's UBE company. As long as you give me a certain amount of time, I am confident that I can conquer it!" Huang Jie said confidently.

It's not that Huang Jie hasn't thought about telling these ideas to some domestic scientific research institutes and companies in the field of advanced ceramics, but they either treat him as a fool or don't care much.

What he wants is to form his own research team and become the director of the laboratory, not a tool man.

But it was too difficult. After all, his qualifications were not deep enough and his achievements were not high enough.

After all, this is just his family's opinion. Who knows whether it is true or not?

Chen Hao did not agree immediately and asked instead: "If I agree to your project, what are your needs in terms of funding and personnel?"

Huang Jie replied without hesitation: "I need 10 million scientific research funds. A research team of about 20 people must have at least 2 full professors, 3 associate professors, or their corresponding full-time researchers (full-time and associate)."

But after saying that, he still felt uneasy in his heart. After all, it was difficult for him to become the director of the laboratory with his qualifications.

"What do you think?" Chen Hao turned to Professor Chen Chong and Professor Fang Haosen and asked.

Chen Chong thought for a moment and whispered: "The idea is very good, but I think it is too hasty just based on his words. We can first ask him to submit a feasibility project application, and then invite some experts in the industry After evaluation, if there is no problem, we will allow the other party to start a group."

"Where are you, Professor Fang?"

Facing the principal's eyes, Fang Haosen chose to echo Chen Chong's words. Bajie Zhongwen website

As for Huang Jie himself, he was already on pins and needles, his palms began to sweat nervously as to whether he could get support from Guanghua University...

Then, Chen Hao's following words made him instantly ecstatic.

"Dr. Huang, I agree with your idea and allow you to establish the [New Structural Materials Laboratory] and serve as the director of the laboratory. At the same time, the laboratory will also be included in the [National Laboratory of Advanced Materials and Semiconductors (in preparation)], accept The leadership of Director Chen Chong and Deputy Director Fang Haosen.”

"And, I will grant you a scientific research fund of up to 30 million yuan, and you can build a team of up to 50 people!"

"I have only one request, and that is to overcome it as soon as possible and fill the gap in this field for the country."

What really made Chen Hao make up his mind was the result of the [Academic Eye] investigation.

[Scientific research project: high-purity silicon nitride powder]

[R\u0026D personnel composition: Dr. Huang Jie]

[R\u0026D success rate: 85%]

One person has an 85% success rate, which has never happened in previous explorations.

Not to mention the success rate once the team is formed.

Our country has developed rapidly in the past 30 to 40 years, but behind this lies an area that many people do not notice. Most of the raw materials are imported.

As a passionate and patriotic scientific researcher, it is his duty to be able to solve the country's technical limitations.

"Dr. Huang, welcome to Guanghua University!"

…

Huang Jie walked out of Guanghua Building with unconcealable joy on his face.

He didn't have high expectations for his trip to Ludao, but he didn't expect it to go surprisingly smoothly.

After completing the entry procedures in the past few days and moving here, he will start setting up a laboratory and carry out research.

Manpower is the most important issue at hand.

Thinking about it, Huang Jie's eyes couldn't help but drift towards Japan.

"It's not like there are no helpers." 1
