Product Description

Product Description

Performance advantages:

high strength, high hardness, wear resistance, corrosion resistance, high temperature resistance of 1200 degrees, good heat dissipation, good thermal shock resistance (not afraid of rapid temperature changes), good insulation performance, low density. The best comprehensive performance in structural ceramics

The characteristics of silicon nitride ceramics are: 

1. High hardness, good wear resistance, low thermal conductivity, good chemical stability, high corrosion resistance

2. High refractory, can withstand high temperatures of 800°C

3. Good chemical stability, can resist acid corrosion at high temperatures

4. High strength, wear resistance, good chemical stability, good biocompatibility, high density

5. It is an inorganic non-metallic material that is resistant to high temperatures, wear and corrosion, with a melting point of up to degrees Celsius, and is one of the best refractory materials in nature
