GMI mullite insulating brick series are made of calcined mullite, imported calcined alumina. They contain stable mullite as main phase structure when fired in elevated temperature with unique processing.
Characterized by good strength, thermal-resistance and low linear shrinkage when re-fired, GMI mullite insulating bricks are suitable for all kinds of industrial heating facilities, and widely used as insulating materials in various kilns for ceramic industry, metal smelting furnaces for foundry and metallurgical industry and chemical insulating area.
6 types of insulating bricks with various size are available, special design per on order.
