65% AL2O3 White Sillimanite Brick 1600 Degree High Temperature Bricks
65% AL2O3 High Compressive Strength White Sillimanite Brick
Sillimanite brick is made of high quality mullite, sillimanite, andalusite, sintered alumina, composite ultrafine powder and special admixtures by high pressure forming and high temperature sintering.It is mainly used for the support arch of the regenerator cell of glass kiln and the bottom of the melting pool. It has the characteristics of high temperature resistance, high compressive strength, thermal shock stability and high temperature creep resistance.
▌FEATURES
1. High temperature resistance；
2. High compressive strength；
3. High temperature creep resistance is superior；
