Chapter 750： Set up 【New Structural Materials Laboratory】

The latest website: "High-purity silicon nitride powder?"

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

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

In recent years, new materials have been the key research and development direction of my country and many countries, and have a wide range of applications in industry, defense, aerospace, electronics, biomedicine and other fields. However, compared with developed countries such as Europe, America, and Japan, my country's advanced ceramic industry generally lags behind the level of developed countries.

What is advanced ceramics?

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

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 in advanced ceramics.

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

It's just that 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.

In today's bearing field, silicon nitride ceramic ball bearings have gradually replaced the 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, low friction torque, good running accuracy and long service life. The "Hexagon Warrior".

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.

What many people don't know is that it is not only the mobile phone chip that is stuck in the neck in China. Just like the lactide mentioned above, the raw material of a degradable straw still needs to be imported.

Similarly, high-purity silicon nitride powder in my country is still restricted by Japan UBE Company and German Stark Company, especially Japan UBE Company strictly restricts the supply to the Chinese market, making domestic high-quality silicon nitride ceramic **** Manufacturers are subject to the supply of raw materials.

Chen Hao and a few people naturally know about these issues, but they have assisted in the art industry, and they have not involved in this field.

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

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

If the other party can really do it, it is incredible, 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 in Japan, I had some cooperation with UBE in Japan, and I also participated in it. I can 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 is a patent problem, it will be more troublesome."

"UBE company certainly won't let me see the core department, but I figured it out myself later, and the patent is 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. Most domestic manufacturers use silicon powder nitridation method. Compared with the 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 UBE is also the only company that can use this method to produce silicon nitride powder."

"But I think there is a synthetic method that will be more pure than the silicon nitride powder prepared by UBE in Japan. As long as you give me a certain amount of time, I have the confidence to conquer it!" Huang Jie vowed.

It's not that Huang Jie didn't think about sharing these ideas with some domestic scientific research institutes and enterprises in the advanced ceramics field, but the other party either regarded him as a fool or didn't care much.

What he wants is to form his own research group and be the director of the laboratory, not a tool person.

But it is too difficult, after all, his qualifications are not deep enough, and his achievements are not high enough.

After all, this is just the words of his family, who knows whether it is true or not?

Chen Hao did not agree immediately, and instead asked: "If you agree with your subject, what do you need for funding and personnel?"

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

Just finished speaking, his heart is still uncertain, after all, with his qualifications, it is still difficult to become the director of the laboratory.

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

Chen Chong thought for a while, and said in a low voice: "The idea is very good, but I think it's too hasty just based on what he said. I can ask him to submit a feasible project application first, and then invite some experts in the industry. After evaluation, if there is no problem, we will allow the other party to open a group."

"How about you, Professor Fang?"

Facing the headmaster's eyes, Fang Haosen chose to echo Chen Chong's words.

As for Huang Jie himself, he was already on pins and needles, and his palms began to sweat nervously. Can he get the support of Guanghua University...

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

"Dr. Huang, I agree with your idea and allow you to set up 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 for Advanced Materials and Semiconductors (in preparation)], accept the The leadership of Director Chen Chong and Deputy Director Fang Haosen."

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

"I only have one request, and that is to conquer it as soon as possible to 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&D personnel composition: Dr. Huang Jie]

【R&D success rate: 85%】

One person has an 85% success rate, something that hasn't happened in previous probes.

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

my country has developed rapidly in the past 30 to 40 years, but behind this, there are areas that many people have not noticed. Most of the raw materials are solved by importing.

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

"Dr. Huang, welcome to Guanghua University!"

...

Huang Jie, who walked out of Guanghua Building, had an undisguised joy on his face.

He didn't expect much from this trip to Ludao, but he didn't expect it to be surprisingly smooth.

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

Manpower is the most important issue at hand.

Thinking of Huang Jie's eyes drifted towards Japan.

"There's no shortage of helpers."

After checking the relevant information for two or three hours, I was dizzy.

Unexpectedly, my country relies on imports for an advanced ceramic powder. Fortunately, some domestic scholars have conquered considerable synthesis technology in the past two years, and the road to scientific research is too difficult.
