Mullite firebrick is made of synthetic mullite, adding organic composite filler according to the required proportion of the product, forming by vacuum extrusion and sintering at high temperature to synthesize light mullite products. With its light weight and excellent thermal insulation properties, Mullite light firebrick is widely used in a variety of thermal equipment hot surface refractory lining or insulation layer, to improve the energy efficiency of equipment to create conditions.
Mullite light refractory brick with mullite main crystalline phase of high alumina refractory material, generally alumina content between 65% and 75%. The refractory temperature of mullite light firebrick can reach more than 1790ºC. Load softening starting temperature 1600-1700ºC. Good thermal shock resistance.
