Khoom siv ntawm Silicon Carbide

Ntshiab silicon carbide yog cov xim tsis muaj xim thiab pob tshab. Muaj silicon carbide yog daj ntseg daj, ntsuab, xiav lossis txawm dub vim yog hom thiab cov ntsiab lus ntawm impurities, thiab nws cov pob tshab txawv nrog nws cov purity. Cov qauv siv lead ua ntawm silicon carbide muab faib ua hexagonal lossis rhombohedral -SiC thiab cubic -SiC (hu ua cubic silicon carbide). -SiC suav nrog ntau qhov sib txawv vim qhov sib txawv sib txawv ntawm cov pa roj carbon thiab silicon atoms hauv nws cov qauv siv lead ua, ntau tshaj 70 hom tau pom. -SiC hloov mus rau -SiC thaum kub siab tshaj 2100 degree. Cov txheej txheem kev lag luam ntawm silicon carbide yog siv cov quartz xuab zeb zoo thiab roj av coke los ua kom nws nyob hauv qhov cub ua haujlwm. Cov smelted silicon carbide blocks yog crushed, ntxuav nrog acid thiab alkali, sib nqus sib nqus thiab sieving los yog dej sib cais los tsim cov khoom ntawm ntau qhov ntau thiab tsawg.
