In Zirconia ceramic family, there is a material can endure the high temperature 2200 degree centigrade. We call it Magnesium Stabilized Zirconia ceramic. It is a refractory material. Although 95% of the composition is zirconium oxide, its performance is quite difference with the white zirconia ceramic(Y2O3 partially stabilized zirconia ceramic) .
From its appearance, it is yellow color and with porosity. We have two kind magnesium stabilized zirconia ceramic. One with low porosity its density is ≤52g/cm3, one with high porosity its density a little higher 5.4-5.6g/m3. But their main composition is almost the same. They can be used in air, vacuum or protective atmosphere environment. Following is the detail of the material data sheet.
