FIELD: chemistry.
SUBSTANCE: invention can be used in manufacturing electrochemical elements, supercapacitors, adsorbents, vacuum and space lubricants, fireproof coatings. Graphite-containing powder material 4 with graphite content not less than 93 wt %, for instance, natural flake graphite, is placed in vacuumed by forevacuum pump 9 closed volume 1 on mirror of iodine heptafluoride liquid phase 5 or above it. Ratio of weight of graphite-containing powder material 4 to iodine heptafluoride weight 5 is from 1:2.21 to 1:5.02. Processing is carried out at 16÷25°C. Composition of obtained compounds corresponds to empirical formula CxFJ0,14·yJF7, wherein x=1÷6, y=0÷0.05.
EFFECT: method is simple, safe and makes it possible to extend nomenclature of obtained products.
