The zircon fire brick is fired in 1600℃ furnace with the zircon content more than 65%.

The zircon fire bricks have compact crystal structure, high density and high mechanical strength. Since zircon brick has good thermal shock stability, low re-fire shrinkage and high temperature creep, and has extremely high chemical stability and resistance to alkaline media, zircon fire brick is widely used in glass industry.

Product Description

Description of Zircon Refractory Brick

Zircon fire bricks are a class of high-performance refractory materials with zirconium compounds (mainly zirconium oxide ZrO₂ or zircon ZrSiO₄) as the core components. In industry, they are mainly used to resist extreme high temperatures, chemical erosion and thermal shock.

Characteristics of Zircon Brick

  • Good slag resistance
  • Long using life
  • Low thermal expansion rate
  • High load softening temperature
  • High abrasion resistance
  • Good thermal shock resistance
  • Thermal conductivity decreases with increasing temperature

Application of Zircon Fire Brick

Zircon fire bricks share common characteristics such as high temperature resistance, corrosion resistance, and thermal shock resistance. For example, their load softening temperature generally exceeds 1650℃, and their bulk density can reach over 4.0 g/cm³. They are widely used in:

Glass industry

Zirconia fire brick is as a core material for the construction and repair of various glass melting furnaces.

Zirconia refractory brick is used as linings for steel ladles, and as key components in continuous casting (such as sizing nozzles).

Zirconia refractory brick is used to withstand various acid and alkali media and ultra-high temperature environments.
