Title:
HIGH ZIRCONIA FUSED CAST REFRACTORY
Document Type and Number:
WIPO Patent Application WO/2013/151107
Kind Code:
A1
Abstract:
Provided is a high zirconia fused cast refractory that is highly durable and is not prone to cracking during refractory manufacturing, when heating increases, when temperature varies during use, or when heating decreases during an operational pause. The high zirconia fused cast refractory is characterized by containing, as a chemical composition, 87 to 96 mass% of ZrO2, 2.5 to 9.0 mass% of SiO2, more than 1.5 mass% but not more than 2.5 mass% of Al2O3, 0.15 to 0.6 mass% of Na2O, 0.3 to 1.3 mass% of K2O, and approximately 0 to 0.3 mass% of Li2O.
