Not only in the field of chips, but also in the field of new materials, which started late and are relatively immature in development, there are the same problems, and the aluminum nitride industry is a typical representative。Aluminum nitride powder is a kind of strategic basic raw materials listed by the national Ministry of Industry and Information Technology, which is widely used and cost-effective heat dissipation raw materials。However, the preparation technology of high-grade aluminum nitride powder has been monopolized by Japanese enterprises for a long time, and the price is extremely high and the export volume of military industry is strictly restricted, which has caused a huge obstacle to the development of related industries in China。After more than two decades of exploration,Xiamen Juhua Technology Co., LTDSuccessfully realized the high grade aluminum nitride powder preparation technology0到1It has become a domestic enterprise with qualified and high-grade aluminum nitride powder batch preparation capability。

Recently, Juporcelain Technology participated2018Entrepreneurial hero Hui audition Xiamen stationSuccessfully shortlisted Xiamen Station20Strong, and will represent Fujian innovation and entrepreneurship strength on the stage of CCTV entrepreneurial heroes。Taking this opportunity, Guanlan Xiaobian interviewed Shi Lei, general manager of Juporcelain Technology, how does this low-key focus and very Chinese feelings of the enterprise achieve zero breakthrough in the industry？

100 billion market demand

Difficult monopoly dilemma to break through

As a raw material with excellent thermal conductivity, aluminum nitride powder is mainly used to make the support and heat dissipation substrate of power semiconductor chips, and is widely used in communication base stations, automobiles, high-speed rail and power grids, consumer electronics, national defense and other fields。Compared with alumina, the main heat dissipation raw material used at present, the thermal conductivity of aluminum nitride is alumina7到10Times, more cost-effective。According to Shi Lei, with the development of science and technology and the updating and iteration of products, the demand for high-performance materials is also increasing。The future domestic construction will exceed1亿个5GThe communication base station has been determined to use aluminum nitride ceramic substrate for heat conduction。未来5年仅5GThe demand for high-grade aluminum nitride powder for communication base stations is in3000Tons or so,The overall domestic demand is about 5,000 tons, and it is conservatively estimated that this will be a market of 100 billion。

But for a long time, the preparation technology of high-grade aluminum nitride powder has been monopolized by Japan Tokusan Company。Domestic high-grade aluminum nitride powder can only be completely dependent on imports, not only expensive, in the important field of national defense military will be limited。Although many scientific research institutions and enterprises are conducting research, they have not been able to make technical breakthroughs。"The technology for the preparation of high-grade aluminum nitride powder is not only a matter of knowing the principle or formula,It is a complete system engineering composed of formula + process + equipmentEach link is the key to product realization and will affect the quality of the product。This process is like cooking, even if we have exactly the same ingredients, but different people, different POTS, different heat will still make completely different tastes。"Shi Lei told us。

With persistent craftsman spirit

Break the industry monopoly

The predicament of the domestic aluminum nitride industry must always be broken by someone, relying on strength, feelings, and focus。"Our goal is to break Japan's monopoly, end the dependence of China's defense industry, semiconductor and other industries on foreign raw materials in the next three to five years, and make contributions to the country and society.。”approach20After years of dedicated research and exploration, Qin Mingli, technology director of Jusci and professor of Beijing University of Science and Technology, has become the top talent in mastering high-grade aluminum nitride preparation technology in China。He is the national 12th Five-Year plan863Project lead expert, has led a number of aluminum nitride research projects。

Juporcelain technology core team

But only the laboratory research results are not enough, how to transform the laboratory results, to achieve large-scale production, is the more important and more difficult problem。2012The project was officially approved by Juporcelain Technology, which began the difficult exploration of the transformation of laboratory results into industry。In addition to the appropriate formula, to really make the product and put it into the market, you also need to have an efficient production process and matching machinery and equipment, and this is almost a blank in the country, even the production equipment needs to design and manufacture。"For us, there are no shortcuts to success, there are just thousands of attempts, and ultimately the results of accumulated experience.。”Shi Lei theory。

Ju porcelain technology production workshop

Due to the rapid consumption of funds in scientific research projects, in the most difficult times, several founders even prepared to sell their own real estate to raise money to tide over the crisis, and sometimes they would not get the understanding of their families。But these in Shi Lei view is only the necessary challenges of entrepreneurship。Hard work pays off, after several years of industrialization exploration, the team finally solved the production problem of high-grade aluminum nitride。With a series of results translated,2016年12月27Xiamen Juhua Technology Co., Ltd. was officially established in Xiang 'an District。

For the reason why I choose to set up a company in Xiamen，Shi Lei told us: "On the one hand，Because the main members of the founding team previously worked and lived in Xiamen，I have feelings for the city of Xiamen.On the other hand，Xiamen Municipal government and Xiang 'an District government support innovation and entrepreneurship is relatively large，There are many supportive policies in place。Now Xiang 'an District is also actively planning the construction of new material industry park, which provides many favorable conditions for Jusci Technology to land in Xiamen。”According to Shi Lei,At present, Jucai Technology is a domestic enterprise that can produce high-grade aluminum nitride powder comparable to international standards。At present, the high-grade aluminum nitride powder produced by Jusa can be completely comparable to Japan's Tokusan Company, and even better in some aspects。Relying on the self-developed short-process production process, Jujia Technology's unit time production capacity is twice that of Deshan Company, while reducing energy consumption per kilogram by 60% and cost by 50%。

With the preparation technology of high-grade aluminum nitride powder, Juporcelain Technology also won the first prize of the new material finals of the sixth Innovation and Entrepreneurship Competition。"Hope to leave their footprints in the long river of history, we have come, this is more important than anything.。In Shi Lei's view, this is the core of Jushi technology corporate culture。

Military to civilian

Expand the application of aluminum nitride market

At this stage, the industry of Jujia technology mainly supplies the military market, and the next step will also expand to the civilian market simultaneously。The reason for choosing such an arrangement, in Shi Lei's view,On the one hand, the current production capacity of porcelain is still lowThe original intention of the establishment of the enterprise is to break the monopoly to solve the import restrictions, so the priority supply of military;On the other hand, the requirements of military enterprises are more stringent than those of civilian useIf we can provide products for military enterprises for a long time, it proves that the quality of our products is excellent, and it is more conducive to the promotion of the civilian market in the later period。The market is in short supply at present，Marketing is not a problem for Jushi，In addition, Chairman Guan Junkai has more than ten years of semiconductor electronic appliances market sales experience，And Toshiba, Shilanwei, SAN 'an and many other well-known brands have had in-depth cooperation，It will be of great help to expand the civil market in the next step。

At present, the most important problem to be solved is to expand the production line and expand production capacity as soon as possible, which is the main purpose of seeking financing at this stage。Shi Lei told us that the jade porcelain plan by the current annual production30Tons lifted to18By the end of the design capacity reached150吨、至19Design capacity reached by the end of the year300吨。It is worth mentioning that in addition to the production and sales of high-grade aluminum nitride powder, the core product, the future Juporcelain technology will also develop another business line -Complex shape aluminum nitride ceramic products。This technology is also leading in the world,2017This technology won the first prize of technical invention of China Nonferrous Industry Association。

Complex shape aluminum nitride ceramic products

Shi Lei introduced:"Our complex shape molding technology is currently internationally leading, and no one in China can do it now, which also ensures that our business with downstream customers of aluminum nitride powder will not overlap。The complex shape aluminum nitride ceramic parts manufactured with this technology are currently only produced in small batches, but we already have high volume production capacity。This project will be carried out gradually in the future。”In addition, in the laboratory of Beijing University of Science and Technology, there are more aluminum nitride ceramic technology in the research and exploration, and there will be more projects put into industrial application in the future。

在前不久召开的两院院士大会上，习近平主席提出："Practice has repeatedly told us that key core technologies cannot be acquired, bought, or negotiated。We should dare to take the road that has not been taken before, strive to realize the autonomy and control of key core technologies, and firmly hold the initiative of innovation and development in our own hands。With strong scientific research strength and persistent, dedicated craftsman spirit, Juporcelain change the industry pattern of the road has just begun。
