Lightweight mullite products are mainly made of mullite raw materials, which are formed and fired by adding alumina powder, calcined powder, clay and a certain proportion of sintering agent. After professional cutting, it has the advantages of precise size, small specific gravity, low thermal conductivity, high temperature resistance and high strength. It is widely used in the lining of hot air furnaces, glass crucibles, low-temperature tunnel kilns, roller kilns and shuttle kilns, and has broad application prospects.
Product use: hot blast stove, glass crucible, tunnel kiln, roller kiln, shuttle kiln, pusher kiln, etc. in household ceramics, ceramics, glass, refractory, petrochemical industries, etc.
