摘要

To provide a powder composition to obtain a tin oxide monolithic refractory which prevents volatilization of SnO 2 in a high temperature zone from an early stage and which also has high erosion resistance to slag. As a refractory mixture, a powder composition for tin oxide monolithic refractory comprising SnO 2 , ZrO 2 and SiO 2 as essential components, wherein the total content of SnO 2 , ZrO 2 and SiO 2 in the refractory mixture is at least 70 mass%, and, based on the total content of SnO 2 , ZrO 2 and SiO 2 , the content of SnO 2 is from 55 to 98 mol%, the content of ZrO 2 is from 1 to 30 mol% and the content of SiO 2 is from 1 to 15 mol%.
