Silicon nitride is a black-gray powder and an important structural ceramic material with high hardness, inherent lubricity and wear resistance. It is an atomic crystal; it does not oxidize at high temperatures, can resist thermal shock, and will not break even if it is heated to over 1000 degree in the air, cooled quickly, or heated quickly. It is precisely because of the excellent properties of silicon nitride ceramics that people often use it to manufacture mechanical parts such as bearings, turbine blades, mechanical seal rings, and permanent molds.

Specification granularity: natural block, 10-100mm, 10-60mm, 3-10mm, 1-3mm, 0-1mm, or customized according to customer requirements.

Packaging: Ton bag packaging (1000kg/bag) or customized according to customer requirements.

1. Structural and performance optimization: Researchers continue to optimize the structure and performance of silicon nitride to improve its mechanical properties, thermal conductivity, optical properties, etc. By controlling the microstructure of the material and adding doping elements, the properties of silicon nitride are improved to better adapt to different application requirements.

2. New synthesis methods: In addition to traditional preparation methods, researchers also try to develop new preparation methods, such as sol-gel method, magnetron sputtering method and hydrothermal synthesis method, to improve the efficiency, purity and controllability of silicon nitride material preparation.

3. Application expansion: Researchers apply silicon nitride to energy storage, optoelectronic devices, biomedicine, sensors and other fields, and actively carry out related application research. For example, the application of silicon nitride in lithium-ion batteries to improve battery performance and cycle life.
