Ceramic Materials
Silicon Nitride (Si3N4)
It is a material with excellent thermal shock resistance and wear resistance, and high strength even at high temperatures
Silicon Nitride is an outstanding Fine Ceramic material with high strength that it maintains even at high temperatures and excellent heat shock and wear resistance. Taking advantage of these characteristics, it is used in a wide range of industries, including parts for molten metal casting, steel manufacturing, milling,and automobile parts.
- Important property :
- Heat Shock Resistance
- Wear Resistance
- High Strength
Features
-
Materials with high strength and toughness at high temperaturesIt is used as a high-temperature structural material for parts of engines, gas turbines and combustors.
-
Low coefficient of thermal expansion and extremely high thermal shock resistanceBecause of its low coefficient of thermal expansion and high thermal shock resistance, it is used for parts under hot environments.
