Abstract

This paper investigates the combustion of magnesium and boron powders in hot steam. A thermochemical analysis reveals theoretical results of such interactions. An experimental investigation demonstrates that stable exothermic oxidation takes place, resulting in actual combustion at 1100 °c for magnesium and 800 °c for boron. The reaction generates large quantity of gaseous products consisting of almost pure hydrogen and corresponding to about 60 per cent of a complete chemical reaction
