1.Mullite Brick Description

Mullite bricks are sintered from mullite raw materials and have a good low thermal expansion, low creep, low thermal conductivity, and good chemical stability. There are two types of mullite bricks. One is sintered mullite bricks, which are made by pressing natural mullite as the main raw material and adding additives. The other is re-sintered mullite brick, which is made by sintering synthetic mullite as the main raw material and additives.
