Sintered Mullite Brick 70% Al2O3 Sintering High Temp Fire Brick
70% Al2O3 Sintering Sintered Mullite White Brick
Sintered mullite brick is made of sintered mullite, fused corundum, fused mullite and special admixture by high pressure forming and high temperature sintering. It is mainly used in the middle and upper part of the glass furnace regenerator, the furnace wall and top of the small furnace, the top of the melting pool, and the feeding passage. It has the characteristics of high temperature resistance, good thermal shock stability and low creep rate at high temperature.
▌FEATURES
1. High temperature resistance；
2. High compressive strength；
3. High temperature creep resistance is superior；
