Zirconium Oxide 99.5%

Zirconia is used as high temperature refractory material, and for cutting blades.The melting-point is very high (about 2700ºC).To maintain its properties zirconium oxide needs to be stabilised by addition of calcium, magnesium, or yttrium oxides.The addition of MgO yields partially stabilised zirconia (PSZ), a relatively coarse microstructure (50-100 micron), used as refractory material (e.g.thermal barriers for high efficiency heat engines), as it retains its properties up to 1100ºC.Additions of yttria (Y2O3) yield tetragonal zirconia polycrystal (TZP), a fine grained microstructure (less than 1 micron) with high strength, toughness, and flexibility (up to 500ºC), used as structural material or for durable cutting blades.
