Zirconia mullite, simply, is a mullite containing zirconia.In order to further improve the corrosion resistance and thermal shock resistance of zirconium mullite and reduce the coefficient of expansion, ZrO2 was introduced into al2O3-SiO2 system to improve the structure of mullite.
Sunrise fused cast zirconia mullite use high-quality bauxite and zircon sand and other raw materials, melting in an arc furnace at high temperature, casting completed.Mainly used for wear - resistant, high - temperature material parts.
