Title:
ALUMINA-ZIRCONIA-SILICA REFRACTORY, GLASS MELTING FURNACE, AND METHOD FOR MANUFACTURING PLATE GLASS
Document Type and Number:
WIPO Patent Application WO/2017/115698
Kind Code:
A1
Abstract:
Provided are: an alumina-zirconia-silica refractory which suppresses exudation of a glassy component from the refractory and is suitable as a refractory for glass manufacturing apparatuses; and a glass melting furnace using the same. The alumina-zirconia-silica refractory includes Al2O3, ZrO2, SiO2, and K2O as essential components, and is characterized by including, in oxide-based mass percentage, 20.0%≤Al2O3≤70.0%, 10.0%≤ZrO2≤55.0%, 4.0%≤SiO2≤25.0%, and 0.8%≤K2O≤12.0%, by Al2O3/SiO2≤7.0 and 0.20≤K2O/SiO2≤0.7, and by a total amount of the essential components being 85% or more.
