Silicon Nitride Ceramic (Si3N4) is one kind of technical ceramic materials which has good performance in room & high temperatrue, its mechanical strength can be kept up to 1200℃. Its hardness and wear resistance performance are at the first rate among all technical ceramic materials. Silicon nitride also has excellent resistance to heat shock and can withstand rapid temperature change. Furthermore, it has good chemical stability and resistance to oxidation. As a result, silicon nitride ceramic has the very good comprehensive properties and are widely applied in different applications.

We are able to produce Si3N4 ceramic parts in custom sizes and shapes, we have good capability to manufacture silicon nitride parts in high size accuracy and fine surface finish as per customers' request, welcome to contact us whenever you have demands.
