英文摘要: The chemical reactivities of two forms of superfine magnesium powders differing in particle size are compared with commercial magnesium powder for nitridation, hydrogenation and Grignard reactions. The chemical reactivities of these magnesium powders are approximately proportional to their specific surface areas or their reciprocal particle diameters. Since the magnesium nanopowders give a specific surface area around three orders of magnitude larger than that of the commercial ones, they can undergo reactions under mild conditions at which the extent of reaction of the commercial magnesium powder is too small to be measured.
