Qaybaha Dhoobada ee Yttria-Xasilay ee Zirconia - Adkayn Sare & Iska caabin Xidhmo
St.Cera waxay soo saartaa qaybo dhoobo ah oo loo sameeyay zirconia iyadoo la adeegsanayo ZrO₂ (Y-TZP) oo yttria-stabilized. Maaddadani waxay bixisaa xoog dabacsan oo heer sare ah (1000 MPa), adkaysi jabka sare (5–8 MPa·m¹/²), iyo adkaysiga Vickers oo ah 13 GPa. Cufnaanta waa 6.03 g/cm³, iyadoo aan lahayn nuugista biyaha. Qaybaha waxaa lagu bixin karaa midab cad ama madow. Habka adkeysiga isbeddelka gaarka ah ee Zirconia wuxuu bixiyaa iska caabin aad u fiican oo ku wajahan faafinta dildilaaca, taasoo ka dhigaysa mid ku habboon qaybaha saameeya saameynta, shoogga kulaylka, ama cadaadiska sare. Qaybaha caadiga ah waxaa ka mid ah kuraasta waalka, tuubooyinka bamka, biinanka hagaha fiilada, qalabka jarista, iyo bushings-ka u adkaysta xirashada.
