Light clay insulation brick is made of refractory clay as the main raw material of Al2O3 content of 30%-48% of the insulation refractory products. Its high porosity, generally 40%-85%; low volume density of less than 1.5g/cm3. Mainly used in industrial furnace insulation materials, can reduce the furnace heat loss, save energy, and reduce the quality of thermal equipment.

High-strength mullite castable with high temperature, can be used as working lining in direct contact with flame to achieve high temperature energy saving;

Mullite lightweight brick can be used as a hot surface working layer refractory lining or insulation layer application. Mainly used for hot blast stove top, blast furnace body and bottom, glass melting furnace heat storage chamber, ceramic sintering kiln, petroleum cracking system dead angle furnace lining, etc.
