摘要: Abstract Nanostructured carbon powders are prepared from graphite powder in a planetary mill using WC, stainless steel, and agate milling tools. The evolution of microstructure chemical reactivity is studied by X-ray diffraction combustion methods, respectively. specific surface area milled samples determined BET measurement the impurity content estimated spark source mass spectroscopy. There no monotonous relationship between particles agglomerations particles. In contrast to contents, distortion atomic short- medium-range order shown be essential for observed enhancement reactivity. A statistical model process formulated used discuss experimental data. As result, an expression dependence temperature on time proposed.
