Selection of reagent ratio for hydrogen production via Al nanopowder oxidation

open access: yesJournal of Physics: Conference Series, 2020
Abstract In the present paper, Al is considered as a basic material for hydrogen production from water because of its high performance, availability, and environmental safety of its reaction products. Here we report the results of experimental trials on the oxidation of Alex-grade Al nanopowder by water when heated and stirred. The plots

Production of metallic nanopowders (Mg, Al) by solar carbothermal reduction of their oxides at low pressure

open access: yesJournal of Magnesium and Alloys, 2016
AbstractThe carbothermal reduction of MgO and Al2O3 in argon flow at low pressure allows to lower the onset temperature of metal vapor formation. Thermodynamic calculations indicate that metal formation begins at 1400 and 1700 K for a primary vacuum (1000 Pa), respectively, for Mg and Al.
