Dab tsi yog Silicon Carbide Cib? Dab tsi yog Kev Siv?
Silicon carbide (SiC) yog ua los ntawm quartz xuab zeb, roj av coke (los yog coke coke), ntoo chips ua raw khoom los ntawm kub kub smelting kuj rauv. Silicon carbide kuj muaj nyob rau hauv cov xwm li ib tug tsawg mineral, moissanite. Silicon carbide tseem hu ua carbonite.
Nyob rau hauv tam sim no C, N, B thiab lwm yam uas tsis yog-oxide high-tech refractory raw cov ntaub ntawv, silicon carbide yog siv dav thiab pheej yig tshaj. Yuav hu ua kub steel xuab zeb los yog refractory xuab zeb. Silicon carbide yog ua los ntawm quartz xuab zeb, muag roj (los yog muag cov thee), ntoo chips los tsim ntsuab silicon carbide nrog ntsev) thiab lwm yam raw cov ntaub ntawv nyob rau hauv lub qhov cub tiv thaiv los ntawm kub refining. Tam sim no, Tuam Tshoj txoj kev lag luam ntawm silicon carbide tau muab faib ua dub silicon carbide thiab ntsuab silicon carbide ob yam, yog hexagonal crystals, lub ntiajteb txawj nqus yog 3.20 ~ 3.25, microhardness yog 2840 ~ 3320kg / mm2.
