In this paper, activated aluminum powder was prepared by magnetic grinding with a homemade equipment and hydrolyzed in alkaline solution to produce hydrogen. The results showed that the prepared aluminum powder could improve hydrolysis reactivity effectively and have high hydrogen yield in alkaline solution (up to 1340 mL/g). It was found that grinding time, reaction temperature and grinding ...
It is difficult to produce fine particles by grinding when only compressive stresses are used, and the width of the size distribution obtained tends to be broadened. Impact grinding gives results intermediate in character between those produced by the application of shear and compressive stresses.
