METHOD FOR PRODUCTION OF METALLIZED THERMALLY EXPANDED GRAPHITE Russian patent published in 1995 - IPC

FIELD: graphite production. SUBSTANCE: method for production of metallized thermally expanded graphite includes graphite oxidation, washing, drying, thermal treatment, treatment with metal hydroxide and reduction of metal in the medium of reducing gas in which oxygen-containing salt or metal hydroxides applied to graphite after washing, and drying is effected at temperature below the temperature of decomposition of applied compound. Thermal treatment is carried out in direct-flow gas under conditions of falling layer at initial volume concentration of 10^-5-10^-3 for 1-8 s. EFFECT: simplified process and reduced energy expenditures. 2 cl, 1 tbl
