thermal conductivity of zircon sand

Classification of Refractory Brick Containing Zirconium

Belonging to an acidic material, the product is made from natural zircon sand (ZrSiO2). Zirconia refractory brick is different from the silica-alumina refractory brick and carbon-containing series of refractory brick, good slag resistance, thermal expansion rate is small, the thermal conductivity decreases with increasing temperature, load softening temperature, wear resistance.
