Wearable Si3n4 Silicon Nitride Si3N4 Ceramic Structural Back Plate

What's Si3n4 Silicon Nitride Ceramic?

Silicon Nitride Ceramic, chemical formula Si3N4, is an important industrial ceramic material with most comprehensive performance. The properties of mechanical strength, fracture toughness, wear resistance, thermal shock resistance are ranking in first class among all industrial ceramics. The mechanical strength of silicon nitride ceramics can be maintained to a maximum working temperature of 1200 ℃. Silicon nitride ceramic will not be infiltrated or corroded by many molten metals or alloys such as aluminum, lead, tin, silver, brass, nickel, etc. The application range of silicon nitride ceramic is very wide, it can be used for wear resistant or corrosion resistant parts in both room temperature and high temperature, it can also withtand rapid temperature change of heating or cooling.

Silicon Nitride Ceramic plates are produced by isostatic molding and high temperature sintered from superfine ceramic powders, the entire plates are fully dense with zero porosity. According to customers' using requirement, silicon nitride plates can be machined into very tight tolerance and polishing surface. The maximum size of silicon nitride plate we can make is 300mm x 300mm, welcome to contact us when you have a demand for silicon nitride plates, we are willing to support for both prototype and batch production.
