Zirconia
Ultra-tough advanced ceramic with exceptional strength, fracture toughness, and wear resistance
The Toughest Technical Ceramic
Zirconia (ZrO₂) stands out among advanced ceramics for its exceptional fracture toughness and strength, often called "ceramic steel." Through stabilization with yttria, magnesia, or ceria, zirconia achieves remarkable mechanical properties that surpass most other ceramic materials.
Our zirconia materials are engineered for the most demanding applications requiring maximum wear resistance, biocompatibility, and mechanical reliability in extreme environments.
