High-temperature refractory ceramic material 3YSZ, kana yatingati tetragonal zirconia polycrystal (TZP), yakagadzirwa ne zirconium oxide yakagadzikiswa ne3% mol yttrium oxide.

Aya magiredhi e zirconia ane zviyo zvidiki uye kuoma kukuru pakupisa kwekamuri sezvo angangoita ese tetragonal. Uye diki (sub-micron) saizi yetsanga inoita kuti zvikwanise kuwana magumo epamusoro uye kuchengetedza kupinza.

Zirconia inowanzoshandiswa seyakagadzikana ine MgO, CaO, kana Yttria kukurudzira shanduko kuomarara. Panzvimbo pekutanga kubuda kuburitsa yakazara tetragonal crystal chimiro, izvi zvinogadzira chikamu checubic crystal chimiro chinogoneka pakutonhora. Tetragonal precipitates inosangana nekushushikana-inokonzeresa chikamu shanduko padhuze neinofambira mberi yekupwanya tip pane kukanganisa. Iyi nzira inoita kuti chimiro chiwedzere apo ichitora huwandu hwakakosha hwesimba, izvo zvinokonzeresa kusimba kunoshamisa kwechinhu ichi. Kupisa kwakanyanya kunokonzeresa kuwanda kwekugadzirisa, izvo zvine mhedzisiro yakaipa pasimba uye zvinokonzeresa 3-7% dimensional kuwedzera. Nekuwedzera masanganiswa ataurwa, huwandu hwe tetragonal hunogona kudzorwa kurova chiyero pakati pekuoma uye kurasikirwa kwesimba.

Patembiricha yemumba, tetragonal zirconia yakagadzikana ne3 mol% Y2O3 (Y-TZP) inoratidza kuita kwakanyanya maererano nekuoma, kukotama simba. Iyo inoratidzawo zvivakwa zvakaita seionic conductivity, yakaderera yekupisa conductivity, kuomarara mushure mekushandurwa, uye chimiro chendangariro mhedzisiro. Tetragonal zirconia inoita kuti zvikwanise kugadzira zvinhu zveceramic zvine huturu hwekurarisa, kukwirira kupfeka kuramba, uye kupedzisa kwepamusoro.

Aya marudzi ezvimiro anogonesa kuti ishandiswe zvakanyanya munzvimbo dzakaita sebiomedical munda wekuisirwa hudyu uye kuvakazve mazino, uye mundima yenyukireya sechivharo chekupisa mumatanda emafuta.
