Zirconia Bricks – Ultra-High Temperature Refractory for Extreme Thermal Environments
What Are Zirconia Bricks ?
Zirconia Bricks (also known as Zirconium Oxide Bricks or ZrO₂ Bricks) are premium refractory materials made primarily from zirconium dioxide (ZrO₂).
These bricks are renowned for their exceptionally high melting point (over 2400°C), outstanding corrosion resistance, and superior thermal shock stability, making them ideal for glass furnaces, kilns, and non-ferrous metal industries.
Due to their low thermal conductivity and high strength at elevated temperatures, Zirconia Bricks are considered one of the most durable and reliable refractory products for critical furnace linings.
Key Features of Zirconia Bricks
- Extremely High Refractoriness (up to 2400°C) – suitable for ultra-high temperature zones.
- Outstanding Corrosion & Erosion Resistance – ideal for molten glass and metals.
- Excellent Thermal Shock Resistance – maintains integrity under rapid temperature changes.
- Low Thermal Conductivity – provides superior insulation and energy efficiency.
- High Chemical Stability – resistant to alkalis, acids, and slags.
- Long Service Life – ensures consistent furnace performance and reduced maintenance.
