To achieve the high efficiency for a comminution of sericite powder with a plate structure, the sericite powder was milled in 1M KNO₃ solution for 0, 0.5, 1, 2, 5, 10 h and compared with the addition of distilled water. It has been found that the mean diameter of the grinded particles decreases until the milling for 1 h, however, increases after l h due to the agglomeration between fine particles The sericite powder milled with 1 M KNO₃ solution for 1 h shows the smallest particle size of 19㎛ and in the case of distilled water, it shows the smallest particle size of 2.4㎛.
