Kev siv ntawm Silicon Carbide
Tso lus
Silicon carbide yog ib qho sib xyaw ua ke ntawm ib qho carbon atom thiab ib qho silicon atom, muaj 70 feem pua silicon thiab 30 feem pua carbon (los ntawm qhov hnyav). Nws tau tshawb pom los ntawm kev sib tsoo los ntawm Edward G. Acheson thaum ua cov pob zeb hluavtaws. Nws yog thawj zaug siv los ua abrasive vim nws hardness thiab muaj peev xwm txiav iav, hlau thiab lwm yam ntaub ntawv. Txij li nws tsis oxidize ntawm yuav luag txhua qhov kub, nws tuaj yeem siv los ua cov khoom siv hluav taws xob. Vim tias nws tseem ruaj khov ntawm qhov kub thiab txias, nws yog dav siv los ua kiln fillers. Vim nws tsis kam rau slag yaig, nws tuaj yeem siv los ua slag kab cib hauv aluminium smelting rauv thiab blast furnace. Txij li thaum nws dissolves nyob rau hauv slag, cov pa roj carbon thiab silicon atoms yuav raug tso tawm raws li them ions (C-4 thiab Si plus 4), yog li nws yog ib qho zoo deoxidizer dav siv nyob rau hauv hluav taws xob rauv steelmaking.
