low glass phase fused cast bricks

Regular cast electrofused Alumina-Zirconia-Silica (AZS) with 36% zirconia and a low silicate phase (14%)

Low glass phase fused bricks are supposed to be a new AZS product for high-end market of glass furnaces. The main component of them is fused alumina-zirconia-silica, which contains 36% ZrO2 and a lower silicate phase (14%). It has very low leakage and quite strong resistance to alkaline attacks, carry-over and creep.

With the efforts in recent years, lots of Chinese enterprises already have been capable of commercial production of these products. The capability has gradually been developed and applied in glass industry.

Recommended Fields Of Application:

Low glass phase fused bricks are widely used in shaped products for high-end glass furnaces, such as fields of optical glass, high alumina glass, TFT-LCD, borosilicate glass, etc. They can be used on the parts which have strict requirements for high temperature performance and glass phase leakage pollution, like crown of oxygen-fuel glass furnace, top spaces of refiner and doghouse crown etc.
