Aluminum nitride-boron nitride composite ceramics, referred to as AlN-BN composite ceramics, refer to a composite of two materials, aluminum nitride (AlN) and boron nitride (BN), based on the principle of composite performance superposition. Composite ceramic products. Aluminum nitride-boron nitride composite ceramics combine the excellent thermal conductivity, low dielectric loss, high elastic modulus and flexural strength of aluminum nitride with the good thermal shock resistance and processing properties of boron nitride. It is a type of high-performance aluminum-based composite material.
The production methods of aluminum nitride-boron nitride composite ceramics include hot press sintering, discharge plasma sintering, vacuum sintering, etc. The hot press sintering method refers to using aluminum nitride and boron nitride as raw materials, in a nitrogen-containing non-oxidizing gas atmosphere, through the addition of sintering aids, pressure sintering, surface micro-nanopore treatment, heat treatment and other steps to generate nitrogen. The method of aluminum nitride-boron nitride composite ceramics has the advantages of short sintering time, high production efficiency, low sintering temperature, and good product molding. It has become the mainstream production method of aluminum nitride-boron nitride composite ceramics.
According to the“Research on Market Monitoring and Future Development Prospects of China’s Aluminum Nitride-Boron Nitride (AlN-BN) Composite Ceramics Industry from 2023 to 2027″ released by the Industrial Research Center Report” shows that aluminum nitride-boron nitride composite ceramics have excellent comprehensive properties. On the basis of combining the advantages of aluminum nitride and boron nitride, they also have long service life and good lubrication performance. Advantages: The application fields cover most application scenarios of aluminum nitride ceramics and boron nitride ceramics, including circuit substrates, microwave energy transmission windows, high-voltage insulating grids, vacuum electrostatic chucks, crucibles, thermocouple protective sleeve production scenarios, etc. The application prospects are relatively broad.
The preparation of aluminum nitride-boron nitride composite ceramics is difficult, and the industry started relatively late. Relevant research did not appear until the early 1990s. The first company to conduct research was Japan’s Kawasaki Steel Company. Since then, many domestic and foreign companies and research institutions have conducted research on it, such as Nippon Steel Corporation of Japan and the 12th Institute of Electronics Industry of China. At present, the aluminum nitride-boron nitride composite ceramic industry is still in the research and development stage, and no company has yet had large-scale mass production capabilities. Among them, Chinese companies that have laid out the research and development track mainly include Pengcheng Tetao, Jingyi New Materials, etc.
Industry analysts said that in recent years, nitride ceramics have become one of the hot areas of materials science research due to their good performance. With the rapid development of communications, electronics and other fields and the increasingly mature composite material production technology, aluminum nitride-boron nitride composite ceramics have emerged and become one of the upgraded nitride ceramic products. Aluminum nitride-boron nitride (AlN-BN) composite ceramic is a new type of high-performance aluminum-based composite material with excellent comprehensive properties and broad application prospects. Its production is difficult. Currently, there is no large-scale mass production capacity in the world. As companies emerge, relevant companies and research institutions will need to speed up product research and development in the future.
