| Abstract: | Selecting the best technological conditions for manufacturing highly purestrontium carbonate from celestite ore by using carbon reduction method is introduced.The highly pure strontium carbonate com be obtained by refining the strontium hydroxide with the method of crystallization seperating,some shortcomings which exist in the traditional manufacture of highly pure strontium carbonate by using industrial strontium carbonate as raw material are overcome. The difficult problem of seperating barium and calcium from a large amount of strontium is also solved.Meanwhile,this technology is simple and its cost is lower.By testing the samples,the average content of strontium carbonate is more than 99%. |
