Zirconia Fire Brick​

Laurel’s zirconia fire bricks are high-density refractory solutions specifically engineered for extreme industrial conditions. With zirconia (ZrO₂) content exceeding 94.5%, these high zirconia bricks provide superior resistance to molten slags, alkali vapors, and thermal shock—making them a preferred choice for high-load, high-temperature furnace applications across the glass, metal, and chemical industries.

These zirconia refractory bricks for sale offer exceptional strength and dimensional stability at service temperatures above 1900°C, significantly outperforming conventional alumina and magnesia-based refractories.

Features

Features

Extreme Thermal Stability (≥1900°C)

Laurel’s zirconia fire brick maintains structural integrity even under prolonged exposure to ultra-high temperatures, delivering long-term protection in glass tank furnaces and incineration systems.

Low Thermal Conductivity

The inherent insulating properties of high zirconia bricks reduce heat loss, enhance energy efficiency, and promote uniform thermal distribution within furnaces.

Corrosion Resistance in Harsh Environments

Whether in acidic slags, alkaline vapors, or molten metals, our zirconia refractory bricks resist infiltration, softening, and wear—ensuring lower maintenance and longer service life.

Dimensional Precision & High Density

Produced under strict quality control, each zirconia fire brick features a dense, low-porosity structure that prevents slag penetration and deformation under mechanical load.

Customization for Industrial Needs

We offer zirconia refractory bricks for sale in various geometries and zirconia content levels, suitable for specialized linings in non-ferrous metallurgy, chemical reactors, and high-purity casting.
