Customized 96% Light Weight Insulation Glass Kiln Coke Oven Refractory Silica Bricks
Product Description :Silica brick is made of high quality silica as raw material, with lime milk and iron scale as mineralizing agent, and with pulp waste liquid as bonding agent, after forming and firing; Zero expansion silica brick is made of fused quartz as raw material, after forming by high temperature sintering 1700ºC;
Light weight silica bricks are made by adding light materials or soap to the ingredients of brick making and then firing them.Product Paramenters : |
