2016 hot selling Mullite Bricks for sale

Mullite Bricks are made of synthetic fused mullite or sintered mullite, pressed by selected shaping processes and fired in high temperature furnaces. Mullite bricks offer high density, low porosity, good hot strength and good sag resistance. Mullite bricks are preferred for high temperature, high load applications, such as at the hot end of regenerative chambers of glass melters, the superstructure of the furnace, and the arch of glass fiber melters, due to their excellent thermal properties, excellent strength at high temperature, great resistance to thermal shock, etc.

Other Refractory bricks with Mullite:

Jm26/Jm26/Jm28/Jm30 Lightweight Mullite Insulating Refractory Brick
Corundum Mullite Bricks
Zircon Mullite Bricks, like high alumina bricks, zirconia bricks are used in the superstructure of glass melting tanks. However, they possess even higher strength and are more resistant to corrosion.
