Zirconium dioxide for aesthetic reasons, or of 2) strong, extremely durable dental prostheses constructed entirely from monolithic zirconia, with limited but constantly improving aesthetics. Zirconia stabilized with yttria (yttrium oxide), known as yttria-stabilized zirconia, can be used as a strong base material in some full ceramic crown restorations. Transformation toughened zirconia is used to make ceramic knives. Because of the hardness, ceramic-edged cutlery stays sharp longer than steel edged products. Due to its infusibility and brilliant luminosity when incandescent, it was used as an ingredient of sticks for limelight. Zirconia has been proposed to electrolyze carbon monoxide and oxygen from the atmosphere
Zirconia Toughened Alumina to withstand heavy loads without succumbing to degradation; giving ZTA many uses in load bearing applications. ZTA’s toughness also means that it has many uses in cutting tools. ZTA and other Alumina are often used is metal cutting applications. Certain engine components, labware, industrial crucibles, refractory tubes can be manufactured using ZTA. Also, certain abrasive applications, such as sandblasting, can also be manufactured using ZTA. Zirconia Toughened Alumina Zirconia toughened alumina is a ceramic material comprising alumina and zirconia. It is a composite ceramic material with zirconia grains in the alumina matrix. It is also known in industry as ZTA.
