Tin oxide refractory and method for its production |
摘要 |
To provide a tin oxide refractory which prevents volatilization of SnO2 in a high temperature zone from an early stage and which also has high erosion resistance to glass.;A tin oxide refractory comprising SnO2, SiO2 and ZrO2 as essential components, wherein the total content of SnO2, SiO2 and ZrO2 in the tin oxide refractory is at least 70 mass %, and, based on the total content of SnO2, SiO2 and ZrO2, the content of SnO2 is from 32 to 98 mol %, the content of SiO2 is from 1 to 35 mol % and the content of ZrO2 is from 1 to 35 mol %. |

1. A tin oxide refractory comprising SnO2, SiO2 and ZrO2 as essential components,
wherein the total content of SnO2, SiO2 and ZrO2 in the tin oxide refractory is at least 70 mass %, and, based on the total content of SnO2, SiO2 and ZrO2, the content of SnO2 is from 76 to 98 mol %, the content of SiO2 is from 1 to 12 mol % and the content of ZrO2 is from 1 to 35 mol %, and wherein when heat treatment at 1,300° C. for 350 hours is conducted, a ZrSiO4 phase and a ZrO2 chase are formed on a sintered body surface of the tin oxide refractory. |
