ABSTRACT:
A method for increasing the Scott density of synthetic and/or natural graphite powders of any particle size distribution, preferably of highly-pure graphite, by subjecting the graphite powder to an autogenous surface treatment. The powder is used, in particular, for producing dispersions, coatings with an increased graphite/binder ratio and increased electric and thermal conductivity, gas and liquid-tight coatings on metal substrates, thermoplastic or duroplastic graphite-polymer composites, or for producing metallic, non-ferrous sintering materials.
