Yttria-stabilized Zirconia Washer

Formula: ZrO₂/Y₂O₃

Form: Washer

Material: Zirconia - stabilized with Yttria

CAS Number: 114168-16-0

Commodity: Ceramics

Standard: ANSI B18.22M-1981, R1990 (Reg)

The Zirconia - stabilised with Yttria Washer is part of Goodfellow's range of ceramic washers. With 9 variations, these washers exhibit high strength and fracture toughness. The addition of yttria stabilizes the zirconium oxide in its cubic crystal structure, improving its mechanical properties. These washers find use in applications requiring thermal shock resistance like gas turbines, automotive engines, and furnace linings. Their low thermal conductivity also makes them suitable for thermal barrier coatings.
