The approach of strontium carbonate - Shanghai xin chemical industry

3, pure strontium carbonate products are preparing strontium chloride purification liquid control heating to 50 ~ 80 ℃, in the presence of ammonium hydroxide ammonium bicarbonate added to a saturated solution of reaction process, in which ammonium hydroxide dosage control in 102 to 120% of the amount of theory, the content of the saturated solution of ammonium bicarbonate in 102 to 120% of the theoretical amount.

4, purification treatment is 8 ~ 12 n hydrochloric acid, control temperature in 60 ~ 90 ℃ dissolve reaction, reaction after fully join in addition to barium, then add ammonium hydroxide until PH = 6 ~ 8 process, including the amount of hydrochloric acid control in 103 to 110% of the amount of theory, in addition to the barium dosage control in the theory of 20 ~ 50%, can be used in addition to the barium chromate or potassium chromate sodium or potassium dichromate or sodium dichromate or ammonium sulfate.
