Magnesium hydrides and their phase transitions

摘要

The mechanism of phase transitions in magnesium dihydrides is explored with the aim how to find the ways for lowering crystal structure stability and facilitate hydrogen desorption. After recapitulation of transition metal hydrides properties, a possible mechanism of fluorite-rutile type displacive phase transition is proposed. (C) 2015 Hydrogen Energy Publications LLC.
