FIELD: electrodes production and constructional graphite production. SUBSTANCE: aim is to expand raw material base of fine and small grain constructional graphites production. Method provides for preparation of composition, that has filter dust, coal pitch and natural graphite, composition oxidation in air medium, production of moulding powder, blanks pressing, carbonization and graphitization. Method allows to substitute coke with filter dust wastes by 100 %. EFFECT: coke is substituted with filter dust wastes. 3 cl, 3 tbl
