Zirconium Oxide Ceramic

Nyob rau hauv sib piv rau lwm cov ntaub ntawv ceramic, zirconium oxide ceramic muaj qhov zoo heev tiv thaiv kev sib kis. Ib qho ntxiv, zirconium oxide raws tej hub muaj qhov ua haujlwm kub kub thiab yog vim li no feem ntau xaiv thaum paub qhov tseeb sib txuas ntawm ceramics thiab hlau.

Lwm qhov zoo tshaj ntawm cov khoom sib xyaw ua ke ntawm sintered zirconium oxide (ZrO2) ceramic yog qhov tsis tshua muaj thermal conductivity thiab tib lub sijhawm muaj lub zog siab. Ntxiv rau, qee qhov zirconium dioxide ceramics muaj cov pa oxygen conductivity. Ntawm tus nqi sab, cov khoom siv ua los ntawm cov zirconium zirconia muaj ntau dua li cov cheebtsam uas ua los ntawm lwm cov nrov oxide ceramic - txhuas oxide alumina. Dawb thiab dub 95 zirconium oxide feem ntau yog siv, piv txwv li cov khoom siv rau cov hlau ua, ua cov khoom siv rau hauv cov txheej txheem ua vuam, ua cov khoom siv rau cov yas thiab cov choj hauv kev kho hniav, raws li lub nplhaib insulating hauv cov txheej txheem thermal thiab raws li cov pa ntsuas ntawm tes hauv. kev sojntsuam lambda.

Xav Paub Ntxiv

Ntshiab ZrO2 yog xim dawb, daj lossis grey thaum nws muaj impurities, thiab feem ntau muaj HfO2, uas tsis yooj yim cais. Lub ntiaj teb' s cov khoom siv zirconium muaj pov thawj yog txog 19 lab tons, thiab zirconium oxide feem ntau yog tsim los ntawm zirconium ore. Muaj peb lub xeev siv lead ua ntawm ntshiab ZrO2 nyob rau hauv lub zog qub: monoclinic zirconium oxide (m-ZrO2), tetragonal zirconium oxide (t-ZrO2) thiab cubic zirconium oxide (c-ZrO2). Cov hom muaj nyob rau qhov sib txawv ntawm cov khoom kub thiab tuaj yeem hloov mus rau txhua qhov chaw sib txawv hauv qhov kub thiab txias. Hauv kev siv tswv yim, kom thiaj li tau txais cov qauv siv lead ua thiab kev ua haujlwm, ntau hom stabilizer feem ntau ntxiv los ua ntau hom zirconia ceramics, xws li yttria stabilized zirconium oxide (Y2O3-ZrO2) thiab cetrium stabilized zirconium oxide (CeO2-ZrO2 )).
