Mullite Refractory Materials
Product Details
Key Specifications/Special Features:Mullite 70Using fine quality natural bauxite as the raw material, M70 is complicated homogenized afterfine selection, and is sintered in high temperature. M70 is characterized with high content ofmullite, high bulk density, high thermal shock resistance, low creep value in high-temperatureand good chemical corrosion resistance. It’s the optimal material for producing various shapedand unshaped refractories and precision casting products.M70 sample mainly contains mullite phase(83-88%) and a little amount of corundum (≤3%), and traces of rutile (TiO2) and the rest is glass phase.
