Preparation Technology of Anhydrous Strontium Chloride

Relying on the advantage of Qinghai strontium resources,the anhydrous strontium chloride was prepared by low-grade strontium carbonate and industrial hydrochloric acid.The process of removal of barium,sulfur and other impurities from low-grade strontium carbonate was studied,and evaporation,concentration,crystallization,filtering and drying processes were also investigated.The quality of products can reach the requirements of the general industrial.Preparation of strontium chloride,not only enrich the types of strontium products in Qinghai province,but also increase the ability of resiting risk of Strontium production enterprises.
