Sintered zirconia mullite refractory composite, its production method and its use

摘要

The present invention relates to a zirconia refractory composite comprising 55% to 65% by weight of Al2O3, 15% to 25% by weight of SiO2, 15% to 25% by weight of ZrO2, and less than 3% by weight of source-derived impurities. A composite material wherein the composite mineralogical composition comprises 65 wt% to 85 wt% mullite and 15 wt% to 35 wt% zirconia. [Selection] Figure 3
