Properties of Zro2 Zirconia Zirconium Oxide Ceramics
(1). Excellent in electrical insulation;
(2). High hardness and wear/corrosion resistance;
(3). High working temperature and thermal shock resistance


Unlike other ceramic materials, zirconium oxide (ZrO2 also known as zirconia) is a material with very high resistance to crack propagation. Zirconium oxide ceramics also have very high thermal expansion and are therefore often the material of choice for joining ceramic and steel.

Another outstanding property combination is the very low thermal conductivity and high strength. In addition, some types of zirconium oxide ceramics can conduct oxygen ions. Components made from this material are significantly more expensive than components made of alumina ceramics. Zirconium oxide ceramics are used, among other applications, as tools for wire forming, as auxiliaries in welding processes, as materials for crowns and bridges in the dental industry, as insulating rings in thermal processes, and as oxygen measurement cells in lambda probes.
