Ternary Intercalation Compound of Graphite with Aluminum Fluoride and Fluorine

Abstract

A ternary intercalation compound of graphite with AlF₃ and F₂, C_xF(AlF₃)_y was prepared under fluorine atmosphere at temperatures of 20-400 °C. The typical 1st stage compound has a composition of C₆F(AlF₃)_0,15 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.
