Zirconia Tej Qws Qws

Cov khoom siv ntawm zirconia ceramic pas nrig yog qhov tshwj xeeb hauv cov tsev neeg ceramic. Cov cuab yeej ua tsoos ceramics feem ntau ua rau cov neeg xav tias yog FRAGILE, tab sis zirconia ceramic tau tawg lub hom phiaj no. Tom qab kev txhim kho tas mus li ntawm cov pa huv thiab kev tsim cov txheej txheem, nws tsis tsuas yog txhim kho nws cov tawv tawv, tab sis kuj siv cov ceramic nws tus kheej kom zoo kawg nkaus tiv thaiv tshav kub, corrosion thiab hnav, tsis tshua muaj thermal nthuav coefficient thiab siab rigidity. Zirconia rods tam sim no tau siv los hloov ntau cov ntaub ntawv alloy hauv ntau qhov kev lag luam.

Cov txheej txheem kev tsim cov khoom ntim khoom siv yog ua los ntawm cov khoom siv raw hloov kho → sib sau → sintering → kev ua, kev sib dhos → kuaj xyuas, tab sis txhawm rau kev hloov pauv ntawm cov yam ntxwv ntawm cov khoom, cov txheej txheem xav tau sib phim nrog cov yam ntxwv ntawm cov khoom siv raw kom tau yam qhov kawg khoom. Cov yam ntxwv ntawm cov ntaub ntawv raw suav nrog cov khoom sib txawv loj xws li particle diameter, particle puab, ntws thiab sau cov yam ntxwv, thiab tshuaj lom neeg. Cov hloov pauv no ncaj qha rau kev cuam tshuam cov ceramic cov txheej txheem thiab cov txheej txheem sintering thiab cov yam ntxwv ntawm cov zirconium oxide pas nrig. Yog li ntawd, paub siab tseeb txog cov hloov pauv no tuaj yeem tswj hwm tus txheej txheem tag nrho.

Ua ntej, txoj kev lag luam tshaj plaws los tsim cov hmoov zirconia yog kom ncaj qha sib xyaw zirconium ore (ZrSiO4) nrog cov pa roj carbon, decompose SiO2 los ntawm arc, thiab tom qab ntawd muab Zr O2 los ntawm ZrC los ntawm txoj kev xaiv. Kev coj dawb huv thiab qhov loj me ntawm zirconia tau los ntawm cov qauv no yog ob qho tib si Nws tsis zoo thiab tsuas yog siv tau los ua cov khoom refractory. Rau zirconia pins thiab zirconia ceramic tus pin kom tau qhov xav tau siab zoo thiab siab lub zog siab, lub ntsej muag cov hmoov nyoos yuav tsum muaj qhov siab ntawm qhov siab thiab qhov siab me me. Yog li, thiaj li ua tau raws li cov kev mob no, cov khoom siv zirconia raw khoom yuav tsum muaj kev huv huv. Cov txheej txheem feem ntau Cov tshuaj tiv thaiv yog kho kom zoo los ntawm kev siv tshuaj lom neeg xws li distillation thiab recrystallization, thiab tom qab ntawd ua kom huv los ntawm cov kev siv lub cev xws li nqus hlau nqus, ua kom sov, ua kom kub, thiab rho tawm. Lub nruj ntawm cov tsoos zirconia ceramic ua los ntawm cov qauv saum toj no tseem tsis txaus. Cov txheej txheem xav tau qhov sib ntxiv ntawm cov tshuaj ruaj khov xws li CaO, MgO, Y2O3 lossis Al2O3. Tom qab homogenization nyob rau hauv high school kub, kev kho cov laus yog nqa tawm ntawm qhov tsim nyog txias txias kom tau txais ntau qhov chaw. Nrig zirconia ceramics (PSZ), nws qhov tawv yog ntau zaus ntau dua li tsoos zirconia ntshiab.
