Nov 16, 2011 Magnesium alanates are potential hydrogen storage materials for PEM fuel cell applications. The method to synthesis the magnesium alanate was presented by ball milling MgH2 and AlCl3 mixtures. Several ball-milling conditions, such as milling temperature, ratio of the mixture, were studied upon MgH2 and AlCl3 mixtures. The IR spectrum of the low temperature ball-milling mixtures

In this thesis the effect of different parameters ball milling time, nickel percentage, hydrogen charging pressure and hydrogen charging temperature in the production of Magnesium-Nickel powders for the storage of hydrogen were studied.
Without catalysis, magnesium hydride forms does not form easily and, even at 350 and 400 o C, the reaction is slow and difficult to complete. In our experiments, magnesium powder was intermixed by a brief ball milling with one of our catalytic compounds and the catalyzed sample was exposed to hydrogen at room temperature under hydrogen pressure ...
a ball mill. My question is, will the friction created by the belt ... figured out a safe way to deal with milling Magnesium. Potassium NitrateMagnesium is a bit unstable when exposed to moisture, I wouldnt use it, but a lot of people do. SulfurMagnesium is unstable
Synthesis of magnesium aluminate spinel MgAl2O4 was investigated by employing ball milling and co-precipitation methods. The starting materials aluminum hydroxides were obtained from the purified sodium hydroxide leaching solution of black dross. The characteristics of the synthesized spinel was analyzed through X-ray diffraction XRD, scanning electron microscopy SEM images.
Problem Slow Hydrolysis of Magnesium Hydride. Promotion of MgH2 hydrolysis via ball milling, hot water treatment or chemical additives have been investigated, but were not found to enhance the chemical conversion rate in a significant manner.
Mechanochemical synthesis or milling allows the production of magnesium hydride with or without additives 18,76 by reactive ball milling RBM, which is basically BM in a hydrogen atmosphere, or by simply BM in an inert atmosphere, respectively. These are the most common techniques used for the production of many metal hydrides.
