Current Status Of Aluminum Nitride Development in China

In our country, the aluminium nitride industry is a typical development in the field of new materials, with its main features being its late start and relatively immature development.  However, as a raw material with excellent thermal conductivity, aluminium nitride is an important raw material for the production of power semiconductor chip support and heat dissipation substrate. With such a huge demand, it is obviously unrealistic to rely only on imports from abroad.

In order to break this situation, in recent years, Chinese materials scientists keep studying and trial production, and finally have broken through the production of high-end aluminium nitride products, the birth of Professor Chongcun said that four representative enterprises. From the professor's answer, it is not difficult to see that Japan also attaches great importance to the rising Chinese manufacturing industry and has made corresponding policy adjustments in this respect.

It is not clear from Professor Tanemura s answer how the Japanese aluminium nitride industry will develop after this. However, it is obvious that Tokuyama, as the leader of the Japanese aluminium nitride industry, has a strong influence in the country. Through its actions, the trend of the Japanese aluminium nitride industry can be determined to a certain extent. Therefore, interested friends may wish to pay more attention to it later.

In a video conference, Professor Tanemura also answered two questions from Professor Li Bo of Tsinghua University's Shenzhen Graduate School: First, the development of new materials industry in Japan compared with China, and second, how he views perovskite solar cells.

Professor Tanemura's answer to the first question was surprising, saying that they were envious of China's willingness to spend so much on research and development in the new materials industry, while Japan has been spending less because of its economic downturn in recent years. As for the second question, Professor Tanemura believes that perovskite batteries still have many problems, but the functionality and stability of perovskite batteries are still a long way from replacing silicon.
