Baranov V.N., Dovzhenko N.N., Gilmanshina T.R., Lytkina S.I., Khudonogov S.A. Research on the dependence of the quality of natural cryptocrystalline graphite on its modes of preparation

Abstract

The research revealed how activation time, type and amount of surface-active additives influenced on an average size and total surface area of crystalline and cryptocrystalline graphite particles, taken from different deposits, and carbon bearing waste materials, during the process of activation in a planetary centrifugal mill, АGО-2. It was shown that the maximum dispersion de-gree of graphite and carbon bearing waste was achieved within 20 minutes of activation without surface-active additives. The most efficient surface-active additives are additives containing sulfo groups in their structure. The amount of such additive should not exceed 3%.

Keywords

Activation, graphite, average size of particles, total surface area of particles, surface-active additives, planetary centrifugal mill АGО-2.
