摘要：

The influence of the mechanical grinding (MG) (under reactive atmosphere of hydrogen) conditions on the physico-chemical properties (crystallography, phase composition, morphology and hydrogen sorption properties) of a Mg + 5% Wt.% Cr2O3 mixture are examined. Both a planetary and a vibratory ball miller have been used. In the case of the planetary ball miller, different rotation speeds (200, 250 and 300 rpm), and ball to powder mass ratios were investigated. It appears that the planetary ball miller allows to obtain finer particles and also more amorphous materials. The relationship between crystallinity, morphology and injected power was established.
