Zirconium dioxide coating on particles of titanium dioxide pigments, as a refractory material, in insulation, abrasives and enamels. Stabilized zirconia is used in oxygen sensors and fuel cell membranes because it has the ability to allow oxygen ions to move freely through the crystal structure at high temperatures. This high ionic conductivity (and a low electronic conductivity) makes it one of the most useful electroceramics. Zirconium dioxide is also used as the solid electrolyte in electrochromic devices. Zirconia is a precursor to the electroceramic lead zirconate titanate ("PZT"), which is a high-K dielectric, which is found in myriad components. The very low
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.
