Less than 10,000 tons a year worldwide,High performance aluminum nitride powder is difficult to produce,why?
Aluminum nitride (AlN) ceramics have good thermal, electrical, mechanical and chemical stability, and are now more ideal substrate materials and electronic packaging materials. The excellent performance of AlN ceramics is directly related to the performance of raw material powder, and the high performance AlN powder is the key to prepare high thermal conductivity AlN ceramics. In foreign countries, the manufacturing process of AlN powder has been quite mature and the commercialization degree is also very high. Previously, according to the [...]
