Product Description

High-quality Silica Brick for Glass Furnace with Excellent Resistance to Alkaline Vapor
The Description:

Acid refractory consisting mainly of squamite, cristobalite and a small amount of residual quartz and glass phase.

Silica content above 94%. True density 2.35g/cm3. It is resistant to acid slag erosion. High temperature strength. Load softening starting temperature 1620 ~ 1670ºC. Long-term use at high temperature without deformation. Low thermal shock stability (heat exchange in water is 1 to 4 times) Natural silica is used as raw material, and an appropriate amount of mineralizing agent is added to promote the conversion of quartz in the billet into quartz. It is slowly fired at 1350 ~ 1430ºC in a reducing atmosphere. When heated to 1450ºC, there is a total volume expansion of about 1.5~2.2%, and this residual expansion will make the cut joints close to ensure that the masonry has good air tightness and structural strength
