METHOD FOR OBTAINING DILATED INTERSTITIAL COMPOUND OF METAL CHLORIDE TREATED GRAPHITE

摘要

FIELD: dilated compounds manufacture. SUBSTANCE: graphite is treated at a temperature of 500-700 C with anhydrous copper chloride vapor or with rare earths metal vapor until a weight gain in the range of 40-140 mass % is attained. The interstitial compound obtained is further treated either with liquid bromine until a weight gain in the range of 80-90 mass % is attained, or with a iodine-monochloride until a weight gain in the range of 30-65 mass. % is attained. The interstitial compound so treated is further heat treated at a temperature in the range of 500-800 C. Method allows to increase the material dilatation extent by 1.5 times and to decrease its specific resistance by 1.5-2 times. EFFECT: increased dilatation property and decreased specific resistance. 1 tbl
