Aluminium oxide (Al2O3), ntau lub npe hu ua alumina, yog siv dav tshaj plaws oxide ceramic khoom . Raws li cov khoom siv raw, Al2O3 hmoov yog tsim los ntawm cov ntxhia pob zeb, los ntawm cov txheej txheem Bayer. Nws cov ntawv thov tau dav dav hauv engineering thiab biomedical applications.
txhuas oxide siv rau dab tsi?
Aluminium oxide yog used rau nws qhov tawv thiab lub zog. Nws daim ntawv tshwm sim, Corundum, yog 9 ntawm Mohs nplai ntawm pob zeb diamond hardness (tsuas yog hauv qab pob zeb diamond). Nws yog dav used ua abrasive, suav nrog ntau tus nqi qis dua rau cov pob zeb diamond. Ntau hom ntawv xuab zeb siv txhuas oxidecrystals.
Puas yog txhuas oxide lom rau tib neeg?
Aluminium oxides nyob rau hauv cov tshuaj lom neeg tsawg thiab tsuas pom muaj tshuaj lom nyob rau hauv siab ntau. Kev nqus pa ntawm aluminium oxide plua plav yuav tsum raug zam, tab sis tsis muaj pov thawj ntawm kev puas tsuaj loj rau lub ntsws cuam tshuam nrog kev nqus ntawm aluminium oxide hmoov av.
Aluminium oxide tsim li cas?
Aluminium(I) oxide yog tsim los ntawm heating Al thiab Al2O3 hauv lub tshuab nqus tsev thaum nyob hauv lub xub ntiag ntawm SiO2 thiab C, thiab tsuas yog los ntawm condensing cov khoom. Cov ntaub ntawv tsis tshua muaj nyob rau ntawm qhov sib xyaw no; Nws tsis ruaj khov, muaj qhov kub thiab txias spectra, thiab nyuaj rau kev txheeb xyuas thiab txheeb xyuas.
Dab tsiyog aluminium oxide hu ua?
Sapphires tuaj nyob rau hauv ntau yam xim, uas los ntawm lwm yam impurities xws li hlau thiab titanium. Lub hardness ntawm ntau hom corundum ua rau lawv haum rau siv raws li abrasives thiab raws li cov khoom hauv cov cuab yeej txiav. Aluminium oxide, tseem hu ua alumina, yog siv hauv engineering ceramics.
