SiO2 96% Fire Resistant Silica Refractory Bricks For Glass Furnace

Hot Sale Cheaper PriceSiO2 96% Super Duty Fire Resistant Refractory BG-96A Silica Brick for Glass Furnace

Products Description

Silica brick is made of quartz stone material, the content of SiO2 is above 93%. It has good resistance to acid slag and good heat conductivity. And the refractoriness is 1690~1710°C, RUL is beyond 1620°C.

SiO2 has different types of crystals in different temperatures, and the transform between the crystals will cause the change of the bulk. So there is a close contact between the changes of SiO2 crystals and the produce, performance and usage of silica bricks. During the heating, there will be changes of the bulk, and cristobalite changes most, then quartz, phosphorus quartz is the slowest of all and it also has good heat-conductivity.Coke oven should use the silica brick with small true density. And the phosphorus quartz is better than others.
