Zirconia ceramics are mainly composed of Zirconia;

At room temperature, yttrium oxide stabilized tetragonal zirconia has good mechanical properties and high bending strength;

Good surface finish and high fracture toughness, and is known as “ceramic steel”;

Coefficient of thermal expansion close to that of metal steel, and it can be easily tested with metal steel; Very good chemical resistance, desulfurization

In addition to acids and hydrofluoric acid, it has good stability to acids, alkalis, glass and molten metals.
