Tetrafluoromethane, kuma aka sani da carbon tetrafluoride, shine mafi sauƙin fluorocarbon (CF4).Yana da ƙarfin haɗin gwiwa sosai saboda yanayin haɗin carbon-fluorine.Hakanan ana iya rarraba shi azaman haloalkane ko halomethane.Saboda nau'ikan haɗin carbon-fluorine da yawa, da mafi girman electronegativity na fluorine, carbon a cikin tetrafluoromethane yana da ingantaccen caji mai ƙarfi wanda ke ƙarfafawa da rage haɗin haɗin carbon-fluorine guda huɗu ta hanyar samar da ƙarin halayen ionic.Tetrafluoromethane shine iskar gas mai ƙarfi.

Tetrafluoromethane wani lokaci ana amfani dashi azaman sanyi mai ƙarancin zafin jiki.Ana amfani dashi a cikin microfabrication na lantarki kadai ko a hade tare da oxygen a matsayin wani abu na plasma don silicon, silicon dioxide, da silicon nitride.
