mechanochemical synthesis: route to novel rock-salt

mechanochemical synthesis: route to novel rock-salt

Sep 14, 2020 · In this process, some ions, like Mn 2+, are easily oxidized, creating a secondary phase. In contrast, ball milling using proper conditions can be done at room temperature and in an inert atmosphere (argon), so it can be easier to maintain the valences of metal ions during the synthesis process. Figure 1b shows a magnification of the (200
