Muscovite | Al2K2O6Si - PubChem

In wet grinding high quality mica scrap is ground with up to 20 wt% water in edge-runner mills. It is then dried and classified to 150, 75, and 45 um (100, 200, and 325 mesh sizes, respectively).Wet ground mica particles have a typical thickness of 0.1 - 0.8 um and a high aspect ratio.
