FM70 is used for making glass kiln lining brick, E-glass sedimentation tanks mullite brick.

Description:

FM70 is a kind of fused mullite made by fusing high purity silicon sand and aluminum oxide in

electrical arc furnace. It has very low Residual carbon, well growed acicular crystal.

FM70 characters good thermal shock resistance and strong anti-corrosive ability.

Applications:

FM70 is used for making glass kiln lining brick, E-glass sedimentation tanks mullite brick, BF low creep sillimanite brick, and ceramic kiln applications.
