zircon corundum brick
product features: melting of zirconium corundum bricks at room temperature has better thermal conductivity, with the temperature rise and become worse, But the temperature exceeds ℃ and Better. Sintered zirconium corundum bricks have higher porosity and uniform microstructure, so the thermal conductivity is lower than that of the casting brick, and the fluctuation is very small with temperature. The resistivity of zirconium corundum brick ( including casting brick and sintered brick ) decreases with the rise of temperature, and the linear expansion rate has the characteristic of reversible transformation.
Product Use: Zirconium corundum brick is mainly used in glass industrial pond Kiln.
