With the high purity raw materials, has features such as low porosity, high density and low content impurity

Made from quality pure natural raw material and selected from natural mullite concentrate after multi-processing, scientific processing and high temperature sintering, guaranteeing the consistency of the product quality.It is widely used to produce many kinds of products with good thermal shock resistance, high temperature property, and low creep property.The product can be a substitute for synthesized mullite so as to lower the production cost.Outer packing:1,000kg/bagN.W.: 1,000kgG.W.: 1,002kgCBM: 0.95
