Mullite Bricks, Corundum Mullite Bricks

Mullite Bricks

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 slag 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:

Insulating Firebricks (IFB) with Mullite for light weight, high strength insulating properties

Corundum Mullite Bricks

Zircon Mullite Bricks, like high alumina bricks and zirconia bricks, are used in the superstructure of glass melting tanks. However, Zircon Mullite Bricks possess even higher strength and corrosion resistance.

KT Refractories distributes Mullite Bricks, Corundum Mullite Bricks, Zircon Mullite Bricks, and insulating firebrick with Mullite of the best quality at the most competitive prices worldwide.
