General Information
CMAX silica brick using high quality silica as raw material to ensure superior performance of silica bricks, the raw materials is high quality dinas rock with SiO2 of 99% min. Its unique structure helps ease forming. Moreover, advantages of complete transformation after sintering and lower residual quartz enable to produce super-duty silica bricks.
Performance:
The silica bricks for glass furnace is characterized by high purity, less impurity, good corrosion resistance, higher bulk density, complete phase transformation, lower residual quartz, high RUL, lower thermal expansion and stable volume at high temperature.
Application
CMAX Silica bricks are commonly applied in
Coke oven
Hot blast stoves
Glass furnace
