More Information
Summary:The invention offers a new method of strontium chloride preparation, the method uses breeze to deoxidize celestite which is dipped into hot water and get solution of strontium sulfide, put sulfureted hydrogen gas into solution of strontium sulfide to make solution of strontium hydrosulphide which reacts with magnesium chloride to get products of strontium chloride and magnesium hydrate, sulfureted hydrogen gas formed in the reaction is used to make strontium hydrosulphide, thus, it circulates like these steps above. The flow of the invention id short, it no need to consume chemical raw material, the raw material used in this invention is simple to get and is cheap, the quality of the product is high; it can get byproduct of magnesium hydrate at the same time and avoid pollution of sulfureted hydrogen, therefore, it has good economical and social benefits, and it is especially suitable for area where the sources of magnesium chloride is abundant.
