Sizing Process Of Kaolin

kaolin | clay | britannica,in its natural state kaolin is a white, soft powder consisting principally of the mineral kaolinite, which, under the electron microscope, is seen to consist of roughly hexagonal, platy crystals ranging in size from about 0.1 micrometre to 10 micrometres or even larger. these crystals may take vermicular and booklike forms, and occasionally macroscopic forms approaching millimetre size are found..
