Ternary Intercalation Compound of Graphite with Aluminum Fluoride and Fluorine

Abstract

A ternary intercalation compound of graphite with AlF3 and F2,Cx;F(AlF3)y was prepared under fluorine atmosphere at temperatures of 20-400°C. The typical 1st stage compound has a composition of C6F(AlF3)o,15 with a repeat distance of 940 pm. Rapid progress in the reaction led of the formation of graphite fluoride, (C2F)n. ESCA spectra indicate that the chemical bond between host graphite and intercalated fluorine has nearly covalent nature similar to that for (C2F)n. © 1981, Walter de Gruyter. All rights reserved.
