摘要：
PURPOSE: A producing method of strontium chloride hexahydrate is provided to control the content of free water using two drying processes for preventing the agglomeration of raw materials to produce the strontium chloride hexahydrate. CONSTITUTION: A producing method of strontium chloride hexahydrate comprises the following steps: producing slurry by inserting water into SrCO2, and inserting hydrochloric acid into the slurry for obtaining a solution; inserting hydrogen peroxide into the solution for oxidizing impurities; increasing the temperature of the solution, and adjusting the pH of the solution into 8~9; compress-filtering the solution, before evaporate-condensing and cool-crystallizing; compress-filtering the crystallized solution for obtaining solids; drying the solids for reducing the free water content less than 2wt%; hot water drying the solids for reducing the free water content less than 0.2wt%; and freezing the solids.
