Cov khoom siv ntawm Silicon Carbide

Ntshiab silicon carbide yog cov xim tsis muaj xim thiab pob tshab. Muaj silicon carbide zoo li lub teeb daj, ntsuab, xiav, lossis txawm dub nyob ntawm seb hom thiab cov ntsiab lus ntawm impurities nws muaj, 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 (lub npe hu ua cubic silicon carbide). Vim muaj qhov sib txawv stacking sequences ntawm carbon thiab silicon atoms nyob rau hauv nws cov qauv siv lead ua, - SiC tsim ntau yam sib txawv, thiab ntau tshaj 70 tau pom. - SiC hloov mus rau - SiC saum 2100 degree. Cov txheej txheem kev lag luam ntawm silicon carbide yog ua kom zoo zoo quartz xuab zeb thiab roj av coke nyob rau hauv lub qhov cub tsis kam. Cov pob zeb ua kom zoo silicon carbide tau ua tiav rau hauv cov khoom ntawm ntau qhov ntau thiab tsawg los ntawm kev crushing, acid-base ntxuav, sib nqus sib nqus, kev tshuaj ntsuam, lossis xaiv dej.
