Unlike other ceramic materials, zirconia (ZrO2, also known as zirconium oxide) is an extremely resistant material to crack expansion. Zirconia ceramics also have a very high thermal expansion rate, making them often the material of choice for joining ceramics and steel.
Products Description
Another excellent combination of properties is extremely low thermal conductivity and very high strength. In addition, certain types of zirconia ceramics conduct oxygen ions. Parts made from this material are much more expensive than those made from aluminum oxide ceramics.
Areas of application for zirconia ceramics include wire molding tools, auxiliary materials in welding processes, materials for crowns and bridges in the dental industry, insulating rings in thermal processes, and oxygen measurement units in λ probes.
