Mullite Insulating Bricks are made of calcined mullite and imported calcined alumina, contain stable mullite as main phase structure after fired in elevated temperature with unique processing. Inimitable technique makes sure that various types of GMI™ insulating brick can meet the requirements of heat-process and chemical-physical application, and well-used in industrial furnaces, heat-processing device and other equipments. With characteristics of high purity, high temperature applicability, corruption resistance, low heat conduct index and thermal capacity, high strength, good thermal shock resistance, good heat preservation, low change in linear shrinkage when re-fired and the good dimension precision, GMI™ insulating bricks are the preferred option of insulating material for various of industrial kilns, smelters and furnaces for ceramic industrial, foundry and metallurgical industry and other heat process equipments.
6 types of insulating bricks with various size are available, special design as per on order.
