Dab tsi yog silicon carbide?

Silicon carbide, yog ib qho khoom siv tsis zoo, cov tshuaj formula SiC, siv quartz xuab zeb, roj av coke (los yog coke), sawdust (tsim ntsuab silicon carbide yuav tsum tau ntsev cov lus) thiab lwm yam raw cov ntaub ntawv los ntawm high-temperature smelting nyob rau hauv lub cub tawg kuj. Silicon carbide - yog ib qho semiconductor uas muaj nyob rau hauv cov xwm li cov ntxhia tsis tshua muaj mozannite. Txij li thaum xyoo 1893, nws tau tsim ntau hauv cov hmoov thiab siv lead ua, uas tau siv los ua cov khoom siv abrasive, thiab lwm yam. Ntawm cov khoom siv high-tech refractory uas tsis muaj oxides xws li C, N thiab B, silicon carbide yog ib qho ntawm feem ntau siv thiab kev lag luam, thiab tuaj yeem hu ua cov xuab zeb kub lossis cov xuab zeb refractory. Kev tsim khoom ntawm silicon carbide hauv Suav teb tau muab faib ua ob hom: dub silicon carbide thiab ntsuab silicon carbide, ob qho tib si yog hexagonal crystals.
