ABSTRACT:
A polycrystalline monolithic sintered alumina refractory body (for use as kiln furniture, and crucibles or nozzles for containment of molten metal) is of fine crystalline sintered aluminum oxide including 15 to 44% by weight of grains of silicon carbide dispersed throughout, such silicon carbide preferably having a sizing between 6 and 46 mesh, but in any case at least 75% being coarser than 100 mesh, such bodies having superior thermal stability and shock resistance.
