ABSTRACT:
A carbon fluoride comprising carbon atoms and fluorine atoms and having a structure in which layers containing fluorinated condensed cyclohexane rings are stacked to form a packing structure, the atomic ratio of fluorine to carbon atoms being 0.5 to 1.8, the carbon fluoride exhibiting a powder X-ray diffraction pattern in which there are peaks respectively at about 13.degree. (2.theta.) and at about 40.degree. (2.theta.) and no peak on the low side of diffraction angle relative to 13.degree. (2.theta.) and exhibiting a spectrum of electron spectroscopy for chemical analysis in which there are peaks respectively due to a monofluorocarbon group and due to a difluorocarbon group, the intensity ratio of the peak due to the difluorocarbon group to the peak due to the monofluorocarbon group being 0.15 to 1.5. The carbon fluoride has a unique property that it is capable of forming a film by vacuum deposition. The carbon fluoride may be produced by the direct fluorination of a pitch or meso-carbon microbeads.
