Abstract
Graphite fluoride in the form of submicron particles is easily obtained at high yield by using, exclusively, acetylene black as the carbon material to be fluorinated with fluorine gas. Use of any other type of carbon black does not give comparable results. Graphite fluoride produced from acetylene black is superior in dispersibility.
