(AZS) Corundum Brick

Fused cast Alumina Brick is formed by the compact structure of α alumina and β alumina crystals in a most ideal proportion which is approximately 50% and 50% respectively,where intertwined crystals of both materials result in a very dense structure.This kind of product has dense structure and no contamination to glass. It is the ideal refractory materials for channels, spouts and working ends of floating glass furnace.

Fused bricks refer to white solids formed by melting pure alumina powder (Al2O3), 65% zirconium oxide (ZrO2) and about 34% zircon sand in an electric furnace and then injecting it into a mold for cooling. Its petrographic structure is composed of the eutectoid of corundum and zirconite and the glass phase. From a facies point of view, it is the eutectoid of corundum phase and zirconite phase, and the glass phase fills between their crystals.
