Apr 21 2020 in general the milling ball or vessel is made from a catalytically active componentThis novel type of catalysis offers the advantage of directly using solid educts that do not require any solubilityCatalyst recycling and separation is most facile as the macroscopic milling ball simply has to be taken out of the vessel after the reaction.
Chemicals that need to be finely powdered before use should be ground separately in a clean mortar amp; pestle or a clean ball mill or tumblerKeep separate equipment for oxidizers and fuelsFor cleaning equipment used for fuels a solvent or sand may be usefulNever grind explosive compounds or mixtures!! use only non-sparking tools.
