Qhov sib txawv tseem ceeb ntawm zirconia thiab plooj (porcelain) yog zirconia yog zirconium dioxide, thaum porcelain yog sib xyaw ntawm hlau thiab nonmetals.
Zirconium yog ib qho oxide ntawm hlau (zirconium hlau). Yav dhau los, nws tau siv los ua cov khoom siv los tsim cov ceramics. Feem ntau, zirconia muaj zog dua porcelain. Txawm li cas los xij, feem ntau ntawm cov khoom siv ceramic ua niaj hnub no yog ua los ntawm cov plooj (porcelain) vim tias cov plooj (porcelain) tuaj yeem tau yooj yim dua.
Zirconia yog dab tsi?
Zirconia yog cov dawb crystalline khoom uas yog ua los ntawm zirconium dioxide. Yog li ntawd, nws yog oxide ntawm zirconium. Cov tshuaj formula yog ZrO2Hauv qhov xwm txheej, peb tuaj yeem pom cov khoom siv no hauv daim ntawv ntawm cov ntxhia baddeleyite. Nws yog tsim los ntawm monoclinic crystalline qauv.
Daim duab 01: Qhov tshwm sim ntawm Zirconium Dioxide
Peb tuaj yeem tsim cov zirconium dioxide los ntawm calcining zirconium compounds los ntawm kev siv lub siab thermal stability ntawm cov compound. Thaum xav txog cov qauv ntawm zirconia, peb tuaj yeem saib peb daim ntawv loj xws li monoclinic siv lead ua qauv, tetragonal qauv thiab cubic crystal qauv. Cov qauv monoclinic thiab tetragonal qauv tshwm sim ntawm qhov sib piv qis thaum cov qauv cubic tshwm sim ntawm qhov kub siab.
Tshuaj, zirconia yog unreactive. Txawm li cas los xij, cov kua qaub xws li hydrochloric acid thiab sulfuric acid tuaj yeem maj mam tua cov khoom. Ntxiv mus, yog tias peb ua kom sov cov khoom no nrog carbon, nws tsim zirconium carbide. Yog tias muaj ob qho tib si carbon thiab chlorine thaum cua sov, nws tsim zirconium tetrachloride.
Cov khoom ntawm zirconia xws li toughness thiab lub zog, ua cov khoom siv no zoo heev hauv kev tsim cov khoom ceramic. Los ntawm kev sib xyaw dopants xws li magnesium oxide (MgO), kev ruaj ntseg ntawm cov khoom nce. Kev siv loj ntawm zirconia yog nyob rau hauv kev kho hniav rau kev tsim cov tawv ceramics. Nws ua raws li kev tiv thaiv txheej rau titanium dioxide txheej. Ntxiv mus, nws tuaj yeem ua raws li cov khoom siv refractive, cov khoom siv insulating, thermal roj teeb txheej, raws li pob zeb diamond stimulants hauv jewellery, thiab lwm yam.
Porcelain yog dab tsi
Porcelain yog hom ceramic uas yog ua los ntawm cov hlau thiab cov khoom tsis yog hlau. Feem ntau, cov plooj (porcelain) yog tsim los ntawm cua sov kaolin hauv ib lub kiln ntawm qhov kub thiab txias. Lub toughness, lub zog thiab translucence ntawm cov khoom no ua rau nws muaj txiaj ntsig zoo hauv cov tais diav. Muaj peb pawg tseem ceeb ntawm cov plooj (porcelain) xws li tawv-paste, mos-paste thiab pob txha suav teb. Cov txheej txheem ntawm cov plooj (porcelain) yog qhov sib txawv heev, tab sis cov khoom tseem ceeb yog kaolinite, uas yog cov av nplaum uas siv los ua cov khoom siv raw rau kev tsim cov plooj (porcelain). Tsis tas li ntawd, peb tuaj yeem siv qee cov khoom siv raw rau kev tsim cov plooj (porcelain), xws li. feldspar, pob av nplaum, iav, pob txha tshauv, quartz, thiab lwm yam.

Cov kauj ruam ntawm kev tsim cov plooj (porcelain) suav nrog kev tsim, glazing, kho kom zoo nkauj thiab tua hluav taws. Lwm yam tshaj li nws siv hauv cov tais diav, muaj qee qhov kev siv tseem ceeb ntawm cov plooj (porcelain) - ua cov khoom siv hluav taws xob, ua cov khoom siv hauv tsev xws li cov vuas, xws li chav dej fittings, thiab lwm yam.
Qhov txawv ntawm Zirconia thiab Porcelain yog dab tsi?
Ob lub zirconia thiab plooj (porcelain) yog cov khoom siv tau zoo uas peb tuaj yeem siv los tsim cov khoom siv ceramic. Qhov sib txawv tseem ceeb ntawm zirconia thiab plooj (porcelain) yog tias zirconia yog zirconium dioxide whereas plooj (porcelain) yog sib xyaw ntawm hlau thiab nonmetals. Feem ntau, zirconia muaj zog dua porcelain. Peb tuaj yeem tsim cov zirconium dioxide siv cov ntxhia baddeleyite thiab cov plooj (porcelain) los ntawm cua sov kaolin av nplaum ntawm qhov kub thiab txias.
Hauv qab infographic qhia txog qhov sib txawv ntawm zirconia thiab porcelain.
Summary – Zirconia vs Porcelain
Ob lub zirconia thiab plooj (porcelain) yog cov khoom siv tau zoo uas peb tuaj yeem siv los tsim cov khoom siv ceramic. Qhov sib txawv tseem ceeb ntawm zirconia thiab plooj (porcelain) yog zirconia yog zirconium dioxide, thaum porcelain yog sib xyaw ntawm cov hlau thiab cov hlau tsis muaj hlau.
