Zirconia Ceramic

Zirconia is one of the most studied ceramic materials. Zirconium dioxide (in its most naturally occurring form) is the mineral baddeleyite. Zirconia begins its life following a thermal treatment process (calcining) of the zirconium dioxide. This zirconia is further processed into different forms, including powder. Ceramic’s zirconia formulations utilize a “ready to press” type of zirconia powder for its near-net shaping manufacturing process.

Tough… Tougher

With a melting point of 2715°C and a boiling point of 4300°C, pure zirconia is extremely tough. However, when heated, phase changes in its physical characteristics reveal a weakness. In its tetragonal phase the expansion of a pure zirconia part results in internal stresses, leading to cracks. This inherent weakness is corrected with the addition of a stabilizer, such as yittria(Yttrium oxide, Y₂O₃), producing YTZP, a yittria partially stabilized zirconia.

A part made of YTZP zirconia remains stable as is moves from its monoclinic (room temperature) phase to its tetragonal (heated) phase and back again, resulting in lessened expansion, and minimal crack propagation. These changes are referred to as Transformation Toughening.

Ceramic manufactures custom ceramic parts of YTZP zirconia for various markets with equally different environments. However, the common threads found making YTZP zirconia the material of choice often includes:

1. Resistance to high abrasion

2. Chemical stability

3. Coefficient of thermal expansion similar to steel

Industrial Ceramic Intriduction

Aluminium Oxide, Al2O3 is the most widely applied and cost effective technical ceramic material. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance. The maximum working temperature is up to 1700 °C with relatively high thermal conductivity. It is also an electrically insulating material with a high electrical resistivity. The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution.
