Fused Zirconia Mullite

Introduction

Fused Zirconia Mullite is made by the fusion of high-quality zirconia sand and industry alumina powder in the electric arc furnace. ln order to further increase the mullite chemical corrosion resistance, thermal shock resistance and reduce the coefficient of expansion, the introduction of ZrO2 in the Al2O3 –SiO2  system can improve the structure of mullite, to make it have good thermal shock resistance, erosion, abrasion  resistance and other advantages.

Fused Zirconia Mullite is a ideal material for production of top fire-proof products such as alumina zircon carbonaceous slide board, stopper, long gate and slide gate, etc.
