The purpose of the invention is to increase the stability of the modification process and reduce the pyroelectric effect and smoke emission. The goal is achieved by the fact that a modifier containing magnesium, calcium, barium, resistive megtalles, copper, silicon, and iron, contains Germanium to strontium at cnt, duishem. Ratio of components, weight,%: For testing GATV t three compositions of the proposed and known modifier. This process is estimated by the prodent of the bottoms with the shape of graphite GF12 and GF13 and GOST 3443-77 of the total number of heats.
