Zirconia hollow ball brick takes fused zirconia hollow spheres as raw material, which is processed by molding and high temperature sintering. Zirconia hollow ball brick has the features of high temperature resistance (the highest temperature ≥2350 ℃), anti-acid corrosion, good insulation properties, high thermal stability.

Zirconia hollow ball brick is widely used in non-metallic materials industry, petrochemical, iron and steel smelting, defense, electronics industry and other fields. For example, it can be used as silicon furnace lining in metallurgical industrial, hydrogen furnace in oil industry, high temperature insulation lining for gasifier apparatus, IF carbide furnace insulation lining.
