Structural transformations in graphite induced by magneto-mechanical-milling in hydrogen atmosphere

摘要: Laser desorption time-of-flight mass spectrometry, X-ray diffraction and Mossbauer spectroscopy methods were used for characterization of phase transformations induced in graphite during controlled reactive ball milling hydrogen atmosphere. During milling, the crystalline structure transformed to nanostructure as proved by studies. The storage capacity nanostructured depends strongly on energy process reached 2.718 wt.% this study. spectrometry method revealed products a variety bare carbon clusters well hydrogenated which may have from one four atoms. Complementary measurements performed using allowed it recognize phases iron compounds observed patterns.
