Silicon Nitride, mainly consistaing of Si3N4, is a gray hard and solid high performance ceramic material sythesized through several chemical reaction methods. WINTRUSTEK offer three sintering methods for Silicon Nitride, Gas Pressure Sintering(GPSN), Hot Press Sintering(HPSN) and Reaction-Bonded Sintering(RBSN). Parts are pressed and sintered by well devoloped methods to achieve the outstanding properties.

This high performance ceramic material has the strongest covalent bond properties next to silicon carbide, it's used as high temperature ceramic components due to its superior hardness, strength and excellent thermal shock resistance, these properties make it ideal for use in mechanical, thermal and wear applications. 

Although Silicon Nitride has high hardness, we owns strong machining ability to meet customers' requests on sophisticated designs, tigth tolerances and smooth surface.
