Calcium carbide yog cov khoom siv tseem ceeb hauv ntau cov txheej txheem muaj cov txheej txheem, suav nrog synthesis ntawm calcium cyanamide los ntawm cov tshuaj tiv thaiv nrog nitrogen. Cov tshuaj tiv thaiv no tau ua rau muaj txiaj ntsig zoo thiab chiv, nrog rau cov khoom lag luam loj hlob xws li urea-raws li cog kev cai lij choj thiab carbide-based hmoov reagents. Cov versatility ntawm calcium carbide txuas mus rau ntau yam kev siv, suav nrog cov tshuaj acetous thiab cov ntaub ntawv acetylene, thiab lwm yam ntaub ntawv xws li roj hmab siv hluavtaws, alconiturile, thiab styrene. Nws yog lub luag haujlwm tseem ceeb hauv kev tsim cov khoom tseem ceeb xws li Vinyl chloride, acetic acid, cum taws acetylene derivatives, cov khoom siv khoom cuav, thiab ething. Ntxiv rau nws siv hauv cov txheej txheem muaj, calcium carbide tseem siv nyob rau hauv cov roj vuam thiab carbide teeb tsim.
