Beschreibung
Zusammenfassung:	It is an object of the present invention to provide a zirconia-based monolithic refractory which is excellent in corrosion resistance and penetration resistance against molten glass, and anti-contamination property for molten glass and which is suitable as a tamping material for a glass furnace, excellent in workability and durability. The present invention provides a zirconia-based monolithic refractory characterized in that it is a monolithic refractory comprising from 70 to 95 mass% of zirconia particles (as calculated as ZrO 2 ) from 2 to 12 mass% of alumina particles, from 1 to 10 mass% of a binder and from 2 to 8 mass% of a glass content (including a glass phase if such a glass phase is contained in the zirconia particles), and it contains substantially no alumina cement in the monolithic refractory.
