Abstract: The paper presents that the graphite mechanical activation (MA) results in the particles size reduction and crystal structure disorder. The estimation of the electric conductivity of high-dispersive graphite powders was performed and the specific electric resistance improving is represented to occur after MA by two orders at the grinding bodies acceleration (1000 m/s2). Thus MA cannot be used for the particles size reduction, the electric resistance value being kept at the initial graphite level in the intensive conditions. The electric resistance of the samples improves from 2 to 6 times after MA at the low grinding bodies acceleration (300 m/s2) therefore MA in the "mild conditions" is more perspective approach to the conductive carbon powders development with the preset particles size.
