Product Description

Low Price Second-Hand Azs Refractory Block for Glass Furnace Wit Good Quanlity
The Description:
Fused brick refers to a white solid formed by melting and internalization of pure aluminum oxide powder (Al2O3) and zircon sand containing about 65% zirconia (ZrO2) and 34% silica (SiO2) in an electric melting furnace and then injecting it into the model for cooling. Its rock phase structure is composed of eutectoid and glass phase of corundum and zirconia clinite. Physiologically speaking, it is an eutectoid of the corundum phase and the zirconite phase, and the glass phase is filled between their crystals.
