Sintering mullite
Sintering mullite

With natural high quality bauxite, by multilevel AL2O3  homogenization technology, sintering mullite is prepared by sintering in high temperature tunnel kilns above 1750°C, which has high bulk density and high porosity. The content of mullite is high, the crystal develops well, which presents the interlaced structure of long column and reticulation, the framework is uniform, the quality is stability, the expanding is uniform, the thermal shock stability is good, the deformation temperature of refractoriness is high, the temperature creep value is low, the rigidity is high, the anti-erosion ability is well. Mullite is the ideal material for preparing casing smooth plate, nozzle brick, ladle brick and open-hearth furnace brick. Mullite is widely applied on iron and steel smelting, Cement kiln and glass industry kiln. It is an ideal high temperature low creep refractory product for high-grade no-shaped refractory, high-grade sanitary body, accurate casting model
