Development of Intercalated Graphite Materials.

Abstract

Graphite intercalation compounds were prepared from highly-oriented pyrolytic graphite and SbF5 or SbF5-HF mixtures using a variety of techniques. These Compounds were characterized by x-ray and gravimetric analysis, c-axis thickness increase, and in some cases by elemental analysis. Room temperature measurements of the basal-plane electrical conductivity and the .07-2.0 eV (17.7-67 microns) optical reflectance were made. High stage SbF5 compounds were found to exhibit a reflectance of over 90% at wavelengths greater than 8 microns. These compounds also were relatively stable in air; lifetimes over 760 hours were observed several times. The highest electrical conductivity, 8 times greater than pure graphite, was observed for Stage 1 compounds; these are unstable in air. No significant differences were observed in the properties of SbF5 and SbF5-HF compounds. (Author)
