Yttria-Stabilized Zirconia (YSZ) Powder
CAS Number: 1314-23-4
Yttria-stabilized zirconia (YSZ) is a premier engineering ceramic featuring the highest fracture toughness among oxide ceramics, achieved through transformation toughening of metastable tetragonal ZrO2. 3 mol% YSZ (3YSZ) is the standard composition for structural applications, while 8 mol% YSZ (8YSZ) is the standard thermal barrier coating and SOFC electrolyte material.
