Yttria Stabilized Zirconia

Description

Dense white powder of high chemical purity containing yttria. Good sintering properties.
Yttria-stabilized zirconia (YSZ) is a zirconium-oxide based ceramic, in which the particular crystal structure of zirconium oxide is made stable at room temperature by an addition of yttrium oxide. These oxides are commonly called "zirconia" (ZrO2) and "yttria" (Y2O3), hence the name.
Chemical Name: Zirconium oxide, Yttria stabilized
Chemical Formula: ZrO2 + Y2O3
