A New Type of the Solid Lubricant Material-Preparation and Properties of Graphite Fluoride

Fluorine gas was produced with the electrolysis of the molten salt KF·2HF, then graphitefluoride was prepared through the reaction between graphite powder and fluorine gas at 500℃.The real density of the graphite fluoride was 2.53g/cm3, its electrical resistivity 3.1×103Ω.cm andits colour greyish white. The graphite fluoride synthesized had a absorption peak of infraredreflection spectra on F-C covalent bond at approximation wavenumber 1219cm-1 and 1350cm-1.By testing friction faCtor for the graphite fluoride, graphite powder and molybdenum disulphide,the experimental results showed that the friction factor of the graphite fluoride was the smollest.Furthermore, technological conditions and special properties of the graphite nuoride were dissussed.
