Magnesiothermic reduction
WebThe magnesiothermic reduction of both metals occurs simultaneously and a complete reduction is confirmed only at 1300 °C. In the Ag 2 WO 4 -C system, silver is reduced first, followed by a stepwise reduction of tungsten in accordance with this scheme: Ag 2 WO 4 → WO 3 → W 18 O 49 → WO 2 → W. Web23 mrt. 2024 · the cycling and reduce the pulverization of the electrode. Recently, Sandhage et al. proposed a facile magnesiothermic reduction to prepare microporous Si structure from 3D silica micro-assemblies.16 However, the low yield and micron scale of the final Si products made them unsuitable as the candidates of electrode materials.
