Silicon carbide (SiC) yog tsim los ntawm kub kub smelting nyob rau hauv lub qhov cub tsis kam nrog raw cov ntaub ntawv xws li quartz xuab zeb, petroleum coke (los yog coke coke), ntoo chips (ntsev yog xav tau los tsim ntsuab silicon carbide).Silicon carbide kuj muaj nyob rau hauv qhov, ib qho tsis tshua muaj ntxhia, moissanite.Silicon carbide tseem hu ua moissanite.Ntawm cov non-oxide high-tech refractory cov ntaub ntawv xws li C, N, thiab B, silicon carbide yog siv dav tshaj plaws thiab kev lag luam, thiab nws tuaj yeem hu ua kub steel grit lossis refractory grit.Tam sim no, Tuam Tshoj txoj kev lag luam ntawm silicon carbide tau muab faib ua dub silicon carbide thiab ntsuab silicon carbide, ob qho tib si yog hexagonal crystals nrog lub ntiajteb txawj nqus ntawm 3.20-3.25 thiab microhardness ntawm 2840-3320kg / mm2.

Silicon carbide muaj plaub qhov tseem ceeb ntawm daim ntawv thov, uas yog: kev ua haujlwm ceramics, qib siab refractories, abrasives thiab metallurgical raw khoom.Cov ntaub ntawv ntxhib silicon carbide tuaj yeem muab tau rau hauv ntau qhov ntau thiab tsis tuaj yeem suav tias yog cov khoom siv high-tech.Daim ntawv thov ntawm nano-scale silicon carbide hmoov nrog cov ntsiab lus siab heev tsis zoo li yuav tsim kev lag luam ntawm nplai hauv lub sijhawm luv luv.

⑴Raws li abrasive, nws tuaj yeem siv los ua cov cuab yeej sib tsoo, xws li sib tsoo lub log, roj pob zeb, sib tsoo taub hau, cov nplais xuab zeb, thiab lwm yam.

⑵ Raws li metallurgical deoxidizer thiab kub resistant khoom.

⑶ High-purity ib leeg siv lead ua tuaj yeem siv los tsim cov khoom siv hluav taws xob thiab silicon carbide fibers.
