Title:
ZIRCONIA BASED MONOLITHIC REFRACTORY
Document Type and Number:
WIPO Patent Application WO2004101466
Kind Code:
A8
Abstract:
A zirconia based monolithic refractory, characterized in that it comprises 70 to 95 mass % of zirconia particles (in terms of ZrO2) and 2 to 12 mass % of alumina particles, 1 to 10 mass % of a binder and 2 to 8 mass % of a glass component (including the glass phase contained in the zirconia particles, if any), and is substantially free of alumina cement. The zirconia based monolithic refractory can be suitably used as a tamping material for a glass tank furnace which is excellent in the corrosion resistance to molten glass, the resistance to permeation, and the anti-staining property to a glass base material, and also exhibits excellent workability and durability.
