YSZ (Yttria-stabilized zirconia) single crystal substrate is one of the earliest materials which applied in high-temperature superconducting films. With high hardness, high firmness, high tenacity, less abrasiveness and good chemical erode resistant property, Zirconium Oxide has already been widely various fields, such as ceramics、refractories、machinery、electronics、optics、space and aeronautics industry、biology and chemistry, etc. The common used Zirconia needs to be doped with Yttrium as a stabilizer. And the usual concentration of it is 13 mol%. YSZ has good mechanical stability and chemical stability with lower cost.
