    2019-03-01  Mechanochemical grinding with a ball mill grinder was tested for the ZSM-5 synthesis to compare with the manual mortar/pestle grinding used in this study. A ball mill grinder was used to grind the solid reagent mixture using the NH 4 Cl as the ammonia source. It was observed that the solid reagent mixture converted to a paste-like phase after only 5 min of ball mill grinding. Similar to the ...
