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.
