JXZM-32
The zircon-mullite brick is made mainly from high-purity corundum and zircon concentrate by high-pressure forming and high-temperature firing. Its main crystalline phases are corundum, mullite and ZO2 (as printed). It withstands high temperature and resists thermal shock and corrosion, and is suitable for glass furnaces.
