Silicon Nitride (Si3N4) is a relatively costly, high-temperature, structural ceramic used where heat resistance, hardness, and strength are a premium. It is very hard, and therefore can be used in high wear applications or applications requiring a fine surface polish. Silicon Nitride is fabricated using either sintering, reaction bonding, hot pressing, or hot isostatic pressing. The material properties resulting from these processes vary considerably.
Silicon nitride ceramics
Our company is a professional production the silicon nitride ceramics, our company produces silicon nitride ceramics has high strength, high hardness, high temperature resistant, wear resistance, corrosion resistance, etc.
