Product Description

High Temperature Resistant Glass Melting Furnace Applied Silica Fire Brick


Silica Fire Brick

Silica refractory brick is fused silica refractorya acid refractory brick which mainly consisting of tridymite, cristobalite, and a small amount of residual quartz and glass phases. The silicon content is 94% or more. True density of the silicon brick is 2.35g/cm3.

CH Refractories has manufactured and installed silicon bricks for more than 30 years, there are many different kinds molds, when manufacturing, which will save much mold casting time. CH Refractories also can design silica firebricks size for you according to your furnace requirements for free and guide you how to install on site.
Fused silica refractory brick is slowly calcined at 1350℃ to 1430℃ under a reducing atmosphere. When heated to 1450℃, there is about 1.5~2.2% of total volume expansion. This residual expansion will make the joints tight and ensure good air tightness and structural strength of the masonry.
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 relationship between the changes of SiO2 crystals and the produce ,performance and usage of silicon bricks. During the heating, there will be changes of the bulk ,and cristobalite changes most, then quartz phosphorus is the slowest of all and it also has good heat-conductivity. Coke oven should use the silica firebricks with small true density. And the phosphorus quartz is better than others.
