Hexagonal boron nitride (HBN/h-BN) is a new functional material and my country’s research and development enthusiasm is high

Hexagonal boron nitride (HBN/h-BN), also known as white graphite, has a hexagonal network structure and is the simplest boron-nitrogen polymer. Hexagonal boron nitride appears as a white powder and has the advantages of corrosion resistance, high temperature resistance, good lubricity, good thermal conductivity, and good electrical insulation. It is widely used in the fields of refractory materials, electronic and electrical, superhard materials, thermally conductive engineering plastics, etc. .

In recent years, my country’s research and development enthusiasm for hexagonal boron nitride has been high and many new developments have been made. In June 2023, Wang Haomin’s research group at the Shanghai Institute of Microsystems and Information Technology, Chinese Academy of Sciences, Hu Weida’s team at the Institute of Physics, and Professor Zhang Zhuhua’s team at Nanjing University of Aeronautics and Astronautics used the photoelectric properties of hexagonal boron nitride to successfully shrink the hexagonal nitride The band gap of boron nanoribbons will be used in the preparation of hexagonal boron nitride optoelectronic devices in the future.

According to the “2023-2028 China Hexagonal Boron Nitride (HBN/h-BN) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center >》shows that as a new functional material, hexagonal boron nitride is widely used in many fields. In the field of refractory materials, hexagonal boron nitride has excellent heat resistance and can be used to produce high-temperature aircraft radomes, rocket engine nozzles, and special metal high-temperature electrolyzers; in the field of electronics and electrical, hexagonal boron nitride has electrical insulation properties and can be used In the production of electronic device packaging materials; in the field of superhard materials, hexagonal boron nitride can be used to prepare oil drilling probes and metal cutting tools. Benefiting from strong application demand, my country’s hexagonal boron nitride production is expected to continue to grow.

Hexagonal boron nitride is the core raw material of cubic boron nitride and is widely used in high-temperature and high-pressure production processes. Cubic boron nitride is a commonly used abrasive and can be used in the field of grinding processing. In recent years, as the prosperity of the superhard materials industry has increased, the market space for materials such as diamond and cubic boron nitride in my country has continued to expand, and output has continued to increase. In 2022, my country’s cubic boron nitride output will reach nearly 700 million carats. With the accelerated development of the cubic boron nitride industry, hexagonal boron nitride has gradually gained a broad market space.

The main players in the global hexagonal boron nitride market include Denka, 3M, MOMENTIVE, Saint-Gobain, etc. The main manufacturers of hexagonal boron nitride in my country include Liaoning Borda Technology Co., Ltd., Zhejiang Yamei Nano Technology Co., Ltd., Suzhou Napu Material Technology Co., Ltd., etc.

Industry analysts said that hexagonal boron nitride has excellent properties such as corrosion resistance and high temperature resistance, and is widely used in many fields. In the future, with the gradual release of downstream demand, the prosperity of my country’s hexagonal boron nitride industry will improve. Hexagonal boron nitride is the core raw material of cubic boron nitride. As the production of cubic boron nitride continues to grow, the market space for hexagonal boron nitride will further expand.
