Silicon nitride is an important structural ceramic material. It is a super-hard substance, which has lubricity and is wear-resistant. It is an atomic crystal; it resists oxidation at high temperatures. Moreover, it can resist the impact of cold and heat. It will not be broken if it is heated to over 1000℃ in the air, cooled rapidly and then heated rapidly. It is precisely because of the excellent characteristics of Silicon Nitride Ceramics that people often use it to manufacture mechanical components such as bearings, turbine blades, mechanical seal rings, and permanent molds. If silicon nitride ceramics, which are resistant to high temperature and difficult to transfer heat, are used to make the heating surface of engine parts, it can not only improve the quality of diesel engines, save fuel, but also improve thermal efficiency.
Remark:
We supply a broad range of silicon nitride ceramic parts, including Ceramic Substrate, ceramic tube,
ceramic shaft, ceramic rod, ceramic bearing, ceramic nozzles and so on.
