4477374 Ternary intercalation compound of a graphite with a metal fluoride and fluorine, a process for producing the same, and an electrically conductive material comprising the ternary intercalation compound

Abstract

A novel ternary intercalation compound of a graphite with a metal fluoride and fluorine, which is represented by the formula Cx F(MFz)y wherein M is Al or Mg and z is an integer corresponding to the valence of M, is produced by contacting a graphite material with a metal fluoride selected from AlF3 and MgF2 in an atmosphere of fluorine gas at a temperature of 0° C. to 400° C. for at least a period of time to effect a weight increase in the graphite. The ternary graphite intercalation compound thus obtained has not only an excellent stability to humidity or moisture but also a high electrical conductivity. The novel ternary graphite intercalation compound according to the present invention may be practically used as a novel electrically conductive material and a catalyst of organic reactions.
