High dense zircon block consists of two kinds of bricks- HDZ-65 and HDZ-68. Zirconia Brick is manufactured using high quality zirconia and zirconium corundum clinker raw materials with ceramic and chemical bonding. Characterized by high bulk density, low apparent porosity, mechanical strength, excellent stability of thermal shocking and resistance to corrosion of glass liquid under load.
