Abstract
Abstract Lubricants having excellent physical properties are composed of a base oil usually used and a high molecular weight inorganic graphite fluoride having a formula of (CF)n as an improver. Graphite fluoride is produced by reacting carbon or graphite with fluorine, halogen fluoride or a higher fluorine compound at a temperature of lower than 550* C.
