Raws li cov khoom ntawmxim av aluminium oxidethiabntsuab silicon carbidezoo sib xws, ntau tus neeg tsis tuaj yeem paub qhov txawv ntawm ob yam khoom. Nov yog qee qhov kev qhia:
1. Cov khoom xyaw sib txawv: Cov ntsiab lus tseem ceeb ntawm ntsuab silicon carbide yog SIC, thiab cov ntsiab lus tseem ceeb ntawm xim av aluminium oxide yog -Al2O3;
2. Xim: Cov xim ntawm cov xim ntsuab silicon carbide yog xim ntsuab tsaus, thiab xim ntawm xim av aluminium oxide yog xim av-liab;
3. Hardness: Lub hardness ntawm ntsuab silicon carbide yog 9.2, thiab hardness ntawm xim av aluminium oxide yog 8.9;
4. Cov khoom siv raw: Cov khoom siv raw ntawm ntsuab silicon carbide yog quartz xuab zeb, roj av coke (los yog coke coke), thiab ntsev. Cov khoom siv raw ntawm xim av aluminium oxide yog bauxite thiab hlau filings;
5. Kev siv: Brown aluminium oxide yog tsim rau kev ua thiab sib tsoo ntawm ntau yam zoo tib yam steels, siab carbon steels, thiab alloy steels vim nws lub zog tensile siab. Nws kuj tseem siv tau los ua ib qho kev hloov pauv thaum qee qhov lwm yam abrasives tsis txaus. Ntsuab silicon carbide yog qhov tsim nyog rau kev sib tsoo zoo ntawm cov ntaub ntawv, xws li xov lossis cov cuab yeej sib tsoo, thiab lwm yam. Cov cuab yeej sib tsoo ua los ntawm ntsuab silicon carbide tuaj yeem ua cov cemented carbide, iav, agate, thiab lwm yam.
Tom qab sib piv cov sib txawv, koj yuav tsum paub qhov txawv ntawm xim av aluminium oxide thiab ntsuab silicon carbide, yog li koj tsis tuaj yeem cuam tshuam lawv.
