Аннотация: This paper is aimed at developing an integrated criterion used to evaluate not only the quality of materials, but also the effect of the material preparation method on the activity of the particles. We studied cryptocrystalline graphite in natural and mechanically activated states from the Kureisckoe deposit. Graphite was activatedПоказать полностьюin a planetary centrifugal mill at Mamina Laboratory of Disperse and Nanostructured, Solid, Viscous and Colloid Materials of Siberian Federal University. In the course of the studies, the authors proposed an empirical criterion based on differential scanning calorimetry to evaluate the energy saturation of filling components for non-stick coatings based on activated cryptocrystalline graphite — the conditional activation criterion. The calculated dependence of this criterion on the activation time proved data earlier obtained: the most optimum graphite activation time in the planetary centrifugal mill is 20 minutes. © GILMANSHINA T.
