Lub hauv paus ntsiab lus ntawm kev tsim khoom tam sim no yog raws li hauv qab no: Lub tetragonal zirconia polycrystalline hmoov uas muaj 3% yttrium oxide nyob rau hauv mole feem pua yog tetragonal theem, nrog rau theem hloov toughening, thiab lub zog yog siab tshaj 1000MPa, tab sis lub teeb transmittance qis dua, thiab nws yog phem tshaj cam khwb cia porcelain cov ntaub ntawv. Ua tau raws li cov kev xav tau ntawm cov hniav zoo nkauj anterior; tag nrho stabilized zirconia hmoov uas muaj 8% yttrium oxide los ntawm mole yog cubic theem.
Vim lub isotropy ntawm lub cubic theem, translucent los yog tag nrho cov ntaub ntawv pob tshab tuaj yeem tau, tab sis vim tias tsis muaj theem hloov Toughened, lub zog tsuas yog kwv yees li 200MI. Los ntawm kev siv cov qauv sib xyaw ntawm tetragonal thiab cubic theem, siv lub zog siab ntawm tetragonal theem thiab lub teeb xa hluav taws xob siab ntawm lub cubic theem, ob-theem cov khoom siv ceramic nrog ob lub zog siab dua thiab zoo dua lub teeb xa tawm tuaj yeem tau txais.
