Hydrogen tungsten bronzes have been synthesized by reactive mechanical alloying monoclinic tungsten (VI) oxide under hydrogen atmosphere. Two milling devices with different energy ranges were used. Regardless of the distinct reaction times, a similar phase evolution was observed with both apparatus. The characterization of the materials was performed by XRD, SEM, DSC and total hydrogen content determination. The final product obtained was a mixture of tetragonal H{sub 0.33}WO{sub 3} and H{sub 0.23}WO{sub 3} bronzes. - Graphical abstract: Hydrogen tungsten bronzes have been synthesized by reactive mechanical alloying (RMA) monoclinic WO{sub 3} under H{sub 2} atmosphere.
