Silicon Nitride Electrical Insulator Description

Silicon nitride electrical insulator is a man-made composite product synthesized through several different chemical reaction methods. Due to its even performance at high temperatures, Si3N4 ceramic is a commonly used ceramic material in the metallurgical industry. It has excellent thermal shock resistance due to the microstructure. The creep and oxidation resistance of Si3N4 is also superior, its low thermal conductivity and high wear resistance also make it an outstanding material that can withstand conditions of most industrial applications.

With low thermal conductivity and resistance to attack by many molten metals, Silicon nitride Si3N4 electrical insulator is used in many RF heating applications. Compared to other conventional insulator materials, Si3N4 electrical insulator has higher strength and thermal shock resistance, which is also an ideal insulator for aerospace applications.

There are 5 different methods to produce silicon nitride ceramics including SRBSN, GPSN, HPSN, HIP-SN, and RBSN, making the application and working material different slightly. In these 5 methods of production, GPSN is most commonly used to produce Si3N4 components.
