Zirconia is used to make crucibles that will withstand heat shock, furnace linings, foundry bricks, abrasives, and by the glass and ceramics industries. It is so strong that even scissors and knives can be made from it. It is also used in cosmetics, antiperspirants, food packaging, and to make microwave filters.
Zirconia is obtained through a reductive clorination. At the end of this process, one can obtain zirconium oxide powder (which is a ceramic and no longer a metal).
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.
To improve the properties of zirconia (ZrO2), other elements are added to the compound to stabilize the molecular structure: ex. Yttrium (Y). Through a mixture and sintering process, the final ceramic structure is stabilized. The Y-TZP is the Yttrium stabilized Tetragonal Zirconium Policrystal.
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.
Stabilized zirconia ceramic products. Mortars and pestles, tubes, rods, plates, valve components, and more.
