This study is to establish the coating technique for synthetic mica and to prepare synthetic mica with the non-aqueous property. The surface coating of synthetic mica is prepared with stearic acid using the high speed stirrer. The characterizations for mica powders coated the stearic acid are carried out by the deposition test, XRD and SEM. The results of research could be coated the stearic acid on the mica by 1600 rpm/min at $70^{\circ}C$ for 10 min. From the observation of SEM was found that the non-aqueous property mica could obtained by mixture ratios for stearic acid and mica, the inner temperature and rotation speed of the stirrer but treated time be unrelated.
