The thermal insulator with mechanical high-performance properties
Zirconia offers the highest flexural strength, fracture toughness, thermal expansion and the lowest thermal conductivity of all oxide ceramics. Its thermal expansion is similar to that of steel, which has a positive effect on force-locked connections with metal parts thus reducing thermal stresses. These properties make zirconia a popular construction material for design engineers.
