Yttria Stabilized Zirconia (YSZ)

Oasis Materials Technology provides YSZ grinding ball, grinding cylinder, jar with lid, tube, powder, etc.

Yttria (3 mol%) Stabilized Zirconia

Partially stabilized Zirconia(PSZ) is a mixture of zirconia polymorphs, because insufficient cubic phase-forming oxide (Stabilizer) has been added and a cubic plus metastable tetragonal ZrO2 mixture is obtained. The most common and widely used PSZ is 3 mol% of Yttria stabilized Zirconia. It contains 3 mol% Yttria (Y2O3), it’s 5.2 ± 0.2 % in weight.
