Silica Bricks

Silica Bricks are made of quartz stone material, the content of SiO2 is more than 96%. The nature and craft process of silica bricks are closely related to the crystal transformation of SiO2. The true density of silica bricks is one of the important indicators of the degree of crystal transformation. Therefore, the true density is an important quality indicator of silica bricks. Generally speaking, the true density of silica bricks should be below 2.38 g/cm 3. The quality of silica brick should be below 2.35 g/cm 3. There are  high quality refractory silica bricks for sale in RS Fire Brick Manufacturer.  Please feel free to Email us for our best price.

Silica Bricks Composition

The raw material for making silica bricks is silica stone. The higher the SiO2 content in the silica raw material, the higher the refractoriness of the silica brick. Impurity constituents are detrimental to the manufacture of silica bricks, such as K2O,Na2O. Because these impurity composition will reduce the refractoriness of refractory products seriously. Other impurity constituents (Fe2O3,CaO,MgO…)will act as flux on silica bricks. From its mineral composition, Silica bricks are mainly composed of tridymite, cristobalite, and a small amount of residual quartz and glass phases.

Silica Bricks Manufacturing Process

Silica brick is made of silica containing more than 96% SiO2, with addition of mineralizers and binders, by kneading, shaping, drying and calcining. The raw materials are crushed and then mixed evenly according to the formulation. Then the raw materials are shaped into the desired shape. After shaping, the products are dried in the tunnel kiln at about 120 ℃ and then fired at 1500℃.

The production process is as follows:

Crushing→Mixing→Pressing→Drying→Firing→Inspection→Packaging→ Warehousing→Delivery

Silica Bricks Properties

Silica bricks belong to acid refractory bricks. Silica bricks have the excellent ability to resist acid slag and acid solution erosion. Besides, Silica bricks have good high temperature strength, high refractoriness under load about 1640-1680℃, high softening point with temperature. What’s more, Silica bricks are also featured with good heat conduction and the refractoriness is 1690~1730°C.

  • Good acid and erosion resistance, high-temperature strength.
  • Natural silica as raw material, plus regular mineralizers and binders.
  • Soften melting temperature is 1680 °C.
  • Ensure good bonding and structural strength of furnace.
  • Good heat resistance and long service life.
  • Low thermal shock resistance.
