ABSTRACT:
A lubricant comprising a partially defluorinated graphite fluoride obtained by exposing a dispersion of raw material graphite fluoride to electromagnetic radiation, followed by the separation of the resulting partially degraded graphite fluoride. The partially defluorinated graphite fluoride is not only excellent in lubricating properties but also has excellent compatibilities with resins, greases and oils. The excellent compatibilities of the partially defluorinated graphite fluoride are effective in preventing the unfavorable deposition of the graphite fluoride in a liquid lubricant composition and advantageously lead to improvement in the moldability of any graphite fluoride-resin composition, thereby enabling the ultimate composition to exhibit excellent lubricating properties.
