Tetrafluoromethane, eo hape e tsejoang e le carbon tetrafluoride, ke fluorocarbon e bonolo ka ho fetisisa (CF4).E na le matla a holimo haholo a tlamahano ka lebaka la mofuta oa bond ea carbon-fluorine.E ka boela ea hlalosoa e le haloalkane kapa halomethane.Ka lebaka la li-bond tse ngata tsa carbon-fluorine, le electronegativity e phahameng ka ho fetisisa ea fluorine, carbon e tetrafluoromethane e na le tefiso e ntle e ntle e matlafatsang le ho khutsufatsa li-bond tse 'nè tsa carbon-fluorine ka ho fana ka sebopeho se eketsehileng sa ionic.Tetrafluoromethane ke khase e futhumatsang lefatše e matla.
Ka linako tse ling Tetrafluoromethane e sebelisoa e le sehatsetsi se tlase sa mocheso.E sebelisoa ho microfabrication ea elektronike feela kapa hammoho le oksijene e le plasma etchant bakeng sa silicon, silicon dioxide, le silicon nitride.
