What is the main material of silica brickIt's common, the kind we see so often!
Higher high temperature strength. The softening start temperature is 1620~1670 degrees. Long term use at high temperature without deformation. The thermal shock resistance is low (the heat exchange in water is 1~4 times). The natural silica is used as the raw material, and a proper amount of mineralizer is used to promote the transformation of quartz into phosphorus and quartz. Slowly sintered at 1350~1430 DEG C in the reducing atmosphere. When heating up to 1450 degrees, the total volume of 1.5~2.2% expands, and the residual expansion can close the kerf and ensure the airtight and structural strength of the masonry.
More than 94% silica content. True density 2.35g/cm3. With acid resistance, slag erosion performance.
An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.
