Formula: ZrO₂/Y₂O₃
Form: Washer
Material: Zirconium Oxide
CAS Number: 114168-16-0
Commodity: Ceramics
Standard:
ANSI B18.22M-1981, R1990 (Reg)
Yttria Stabilised Zirconia (YSZ) Washer offers the toughness, chemical stability, and thermal resistance of stabilized zirconia in a precise flat-ring geometry suited for high-performance fastening and sealing. Yttria additions prevent phase degradation, ensuring dimensional integrity at elevated temperatures. Industries including aerospace, chemical processing, and electronics employ YSZ washers in chemically inert seals, non-magnetic spacers, and insulating fixtures. Specific applications include insulating washers in high-voltage assemblies, chemically stable seals in corrosive fluid systems, and precision components in high-vacuum chambers. In research, YSZ washers are investigated for phase stability, ionic transport, and compatibility with novel electrode coatings. Their combination of resilience and insulating capability makes them vital in electrochemical, aerospace, and high-performance fastening technologies.
