Cov Lus Qhia Yooj Yim
Zirconia yog cov khoom siv dav dav. Nws muaj peb ntu nrog cov qauv sib txawv, uas yog lub theem monoclinatic, theem tetragonal theem, thiab cov ntu ntu. Cov ntsiab lus sib txawv tuaj yeem muaj kev cuam tshuam zoo ntawm kev ua yeeb yam ntawm cov khoom siv zirconia ceramic. At present, the most common zirconia materials are yttrium-stabilized zirconia. 3mol yttria-stabilized zirconia has better toughness and fracture resistance, while 5mol yttria-stabilized zirconia has better phase stability at high temperatures. Yttria ruaj khov zirconia cov phiaj tuaj yeem tsim los qhia cov xim sib txawv, xws li dawb, xim dub, los ntawm doping nrog sib txawv hlau ions.

Cov khoom ntawm yttria ruaj khov zirconia ceramics
Cov Khoom Siv Zoo Tshaj Plaws Thiab Hnav Kuj
Nrog ib tug vickers hardness txog li 1175 GPA thiab ib qho mapa elastic txog txog li 200 GPA, Zirconia muaj qhov hnyav, ua rau nws muaj kev haum rau ib puag ncig.
Tshuaj Muaj Peev Xwm
Zirconium oxide cov tshuaj inertness ua rau nws zoo heev rau kev ua yeeb yam tshuaj lom neeg thiab tiv taus corrosion los ntawm ntau yam ntawm corrosive tshuaj.
High Pob Txha Taug Kev
Tus ncej muaj pob txha lov tod txog li 9 MPA31 / 2 thiab tsis yog tawg yooj yim thaum raug cuam tshuam lossis cuam tshuam.
Du nto thiab meej cov txheej txheem tsim khoom
Cov khoom lag luam nto tuaj yeem ua polished, thiab txoj kev du, thiab hnav kom zoo nkauj thiab hnav, thiab txhim kho cov efficiency thiab lub neej ntawm kev txav chaw.
Thermal ruaj khov
Zirconium oxide muaj qhov thermal conductivity ntawm 2.5 w / (mind rog poob siab ruaj khov (△ t yog 250 degree), ua rau ib puag ncig uas muaj qhov kub loj hloov.
Cov ntawv thov ntawm Zirconia Ceramic
Muaj Cov Ntawv Thov
Xws li milling tshuab qhov chaw, zawv zawg qhov chaw, thiab tuaj yeem ua cov cuab yeej ntawm kev txiav. Cov ntawv thov no feem ntau yuav tsum tau cov khoom los tiv thaiv cov tshuab puas yam tsis muaj kev ua tsis tiav.
