Silica Carbide Brick Introduction
Silica carbide fire Brick is made of SiC as the main material, which include 72%~99% SiC content, which have features of high thermal conductivity, great wear resistance, good thermal shock resistance, low heat expansion coffocient, etc. Silicon carbide fire brick is a kind of very important refractory materials for various furnaces and kilns which are of high temperature and high strength erosion atmosphere.
Silica Carbide Brick Properties
- High heat conductivity
- Good abrasive resistance
- Great thermal shock resistance
- Excellent erosion resisting
- Strong resistant to acid and alkali slag erosion
- High strength
- Low heat expansion coefficient
