Refractory Silica Brick

High Density Silica Fire Brick

High density silica fire brick introduction

High density silica fire brick belongs to acid refractory material, silica content is more than 94%, the true density of 2.38g/cm3. With acid slag erosion resistance, high high temperature strength, load softening starting temperature 1620 ~ 1670℃, long-term use at high temperature without deformation.

High density silica fire brick features

Silica fire brick has the characteristics of high purity, high strength, wear resistance, compact, and high thermal shock stability, volume stability and low creep performance.
