Qhov sib txawv tseem ceeb ntawm zirconia thiab aluminium oxide yog tias zirconia tshwm sim hauv cov qauv siv lead ua monoclinic thaum txhuas oxide nyob hauv cov qauv siv lead ua trigonal.
Zirconia thiab txhuas oxide yog cov tshuaj tsis muaj zog thiab yog cov oxides. Ob lub tebchaw no tshwm sim hauv cov dawb crystalline solid-state ntawm tus qauv kub thiab siab.
Zirconia yog dab tsi?
Zirconia yog ib qho inorganic oxide compound uas muaj cov tshuaj formula ZrO2 Nws lub npe tshuaj yog zirconium oxide; Nws muaj ob lub atoms oxygen rau ib lub zirconium atom hauv ib lub molecule. Nws zoo nkaus li dawb crystalline khoom, muaj cov qauv siv lead ua monoclinic. Txawm li cas los xij, peb tuaj yeem tsim cubic structured zirconia nrog cov xim sib txawv los siv ua gemstones. Peb tuaj yeem tsim zirconia los ntawm calcining zirconium tebchaw, siv nws cov cuab yeej ntawm thermal stability.

Ntxiv mus, qhov sib xyaw no tuaj yeem tshwm sim hauv peb lub pob zeb loj ntawm qhov kub sib txawv: monoclinic, tetragonal thiab cubic. Txawm li cas los xij, feem ntau ruaj khov thiab tshwm sim hauv daim ntawv yog cov qauv monoclinic. Chemically, cov compound no yog unreactive, tab sis muaj zog acids xws li HF thiab H2SO4 tuaj yeem maj mam tua nws. Tsis tas li ntawd, yog tias peb ua kom sov no nrog carbon, nws hloov mus rau hauv zirconium carbide, thiab yog tias muaj chorine zoo li, ces nws tsim zirconium tetrachloride. Cov tshuaj tiv thaiv no yog lub hauv paus rau kev ua kom huv ntawm zirconium hlau.
Thaum xav txog kev siv zirconia, nws yog qhov tseem ceeb hauv kev tsim cov ceramic, ua cov khoom siv refractory, ua cov insulator, ua abrasives thiab enamels, thiab lwm yam. Tsis tas li ntawd, nws cov ionic conductivity siab ua rau nws muaj txiaj ntsig zoo li cov khoom siv electroceramic..
Aluminium Oxide yog dab tsi?
Aluminium oxide yog ib qho inorganic oxide compound uas muaj cov tshuaj formula Al2O3 Nws yog qhov ruaj khov tshaj plaws thiab tshwm sim oxide ntawm aluminium. Feem ntau, peb hu nws alumina. Lawm, cov compound no tshwm sim nyob rau hauv crystalline, alpha polymorphic theem. Nws zoo nkaus li cov khoom dawb, thiab nws cov qauv siv lead ua yog trigonal. Ntxiv mus, corundum yog daim ntawv tshwm sim ntawm txhuas oxide.

Thaum xav txog cov khoom ntawm cov khoom sib xyaw no, nws yog cov khoom siv hluav taws xob zoo heev, tsis muaj dej hauv dej, tiv taus huab cua thiab tiv thaiv aluminium hlau nto ntawm oxidation ntxiv. Ntxiv mus, nws yog ib qho amphoteric tshuaj. Qhov ntawd txhais tau tias; Nws tuaj yeem hnov mob nrog ob qho tib si acids thiab cov hauv paus kom dhau los ua cov tshuaj tiv thaiv kev ua ntsev thiab dej.
Muaj ntau daim ntawv thov rau txhuas oxide:
- As cov khoom siv refractory
- Kev tsim cov ceramic thiab abrasives
- Raws li cov khoom siv rau cov yas
- As ib qho khoom hauv iav
- Kev tshem tawm cov dej ntawm cov kwj dej
- Raws li catalyst rau ntau cov organic synthesis tshuaj
- Raws li cov khoom hauv cov xim, thiab lwm yam.
Qhov txawv ntawm Zirconia thiab Aluminium Oxide yog dab tsi?
Feem ntau, Zirconia yog ib qho inorganic oxide compound uas muaj cov tshuaj formula ZrO2 hos Aluminium oxide yog ib qho inorganic oxide compound uas muaj cov tshuaj formula Al 2 O3 Tab sis, qhov tseem ceeb tshaj, qhov sib txawv tseem ceeb ntawm zirconia thiab aluminium oxide yog tias zirconia tshwm sim hauv cov qauv siv lead ua monoclinic thaum txhuas oxide nyob hauv cov qauv siv lead ua trigonal.
Ntxiv mus, zirconia yog qhov yooj yim me ntsis vim tias nws hnov mob maj mam nrog cov acids muaj zog xws li HF thiab sulfuric acid; Txawm li cas los xij, txhuas oxide yog amphoteric, thiab nws tuaj yeem ua rau cov kua qaub thiab cov hauv paus tsim cov ntsev thiab dej. Tsis tas li ntawd, qhov sib txawv ntxiv ntawm zirconia thiab aluminium oxide yog lawv cov reactivity. Chemically, zirconia yog unreactive, tab sis txhuas oxide yog reactive.
Summary – Zirconia vs Aluminium Oxide
Zirconia yog ib qho inorganic oxide compound uas muaj cov tshuaj formula ZrO2 thaum Aluminium oxide yog ib qho inorganic oxide compound uas muaj cov tshuaj formula Al 2 O3 Qhov sib txawv tseem ceeb ntawm zirconia thiab txhuas oxide yog tias zirconia tshwm sim hauv monoclinic siv lead ua qauv thaum txhuas oxide nyob hauv cov qauv siv lead ua trigonal.
