Abstract
To provide a tin oxide refractory which prevents volatilization of SnOin a high temperature zone from an early stage and which also has high erosion resistance to glass. A tin oxide refractory comprising SnO, SiOand ZrOas essential components, wherein the total content of SnO, SiOand ZrOin the tin oxide refractory is at least 70 mass %, and, based on the total content of SnO, SiOand ZrO, the content of SnOis from 32 to 98 mol %, the content of SiOis from 1 to 35 mol % and the content of ZrOis from 1 to 35 mol %.
