ALUMINA-ZIRCONIA-SILICA FUSED CAST REFRACTORY AND GLASS MELTING FURNACE
Provided are: an alumina-zirconia-silica (AZS) fused cast refractory in which generation of cracks is further prevented during production of the AZS fused cast refractory and in which grinding and polishing parts are reduced; and a glass melting furnace using the same. This AZS fused cast refractory comprises, in mass% on an oxide basis, 30 to 75% of Al2O3, 20 to 55% of ZrO2, 5 to 15% of SiO2, 0.12 to 1.52% of Na2O, and 0.11 to 1.46% of K2O, and satisfies formulas (1) and (2). 0.080≤(Na2O+K2O/1.52)/SiO2≤0.140 (1) 0.2≤(K2O/1.52)/(Na2O+K2O/1.52)≤0.6 (2) (In formulas (1) and (2), the chemical formulas represent the contents (mass%) of the chemical formulas in the refractory.)
