  • Playing Ball With The Haberbosch Process Advanced

    Dec 23, 2020 In an eye-opening recent report it was demonstrated that the ammonia synthesis process could be powered mechanochemically in a simple ball mill laboratory experiment under the seemingly very gentle conditions of 45 C and 1 atmosphere. The mechanochemical ammonia yield reported was found to be significantly higher than the HaberBosch.
