Yttria Stabilized Zirconia (YSZ) Ceramics

Yttria Stabilized Zirconia (YSZ, YTZP) is the most common form of stabilized zirconia ceramic. Typical composition of Yttria Stabilized Zirconia is 94.7% ZrO2 + 5.2% Y2O3(weight percentage) or 97 ZrO2 + 3% Y2O3 (mol percentage)

Compared with alumina, zirconia has much larger density and better wear and corrosion resistance. Yttria Stabilized Zirconia is a better material for mechanical parts. It is the most durable material for ceramic mechanical parts and grinding jars. Yttria Stabilized Zirconia (YSZ, YTZP) also has great corrosion resistance. YSZ ceramics are widely used to handle corrosive chemicals and molten metal. It also provide low contamination due to the wear resistance and corrosion resistance.
