Re-sintered electric fused zircon mullite bricks
- Description
-
Zircon mullite bricks are made from Australian zircon sand, electric melting mullite, electric melting white corundum, composite ultrafine powder, and special additives, formed under high pressure and sintered at high temperatures. They are used in small glass furnace kilns, melting pools, upper structures of working pools, and feeding channels. They feature high temperature resistance, shock resistance, resistance to slag and glass liquid erosion, thermal shock stability, and good high-temperature creep resistance.
