ABSTRACT:
Fluorinated graphite fibers comprising an intercalated compound of graphite fibers, having a three-dimensional crystal structure in which carbon hexagonal network faces are substantially in parallel with the axis of the fibers, and are oriented in a coaxial manner, and fluorine, wherein the length of repeating periods in the direction of the C-axis of the crystals coexist within a range from 5 to 24 .ANG.. The fluorinated carbon fibers are manufactured by graphitizing gas phase-grown carbon fibers obtained by thermally decomposing a hydrocarbon compound in a non-oxidative atmosphere in the presence of a catalyst supported on a substrate, or by bringing ultra-fine metal catalyst particles suspended in a high temperature zone into contact with a hydrocarbon compound, thereby obtaining graphite fibers having a three-dimensional crystal structure in which the carbon hexagonal network faces are substantially in parallel with the axis of the fibers and are oriented in a coaxial manner, and then bringing them into contact with fluorine.
