Strontium carbonate technology invention

5 to 7 hours of the process, including the amount of ammonium hydroxide used as lapis lazuli 120 ~ 180%, the amount of the amount of ammonium bicarbonate as 130 ~ 170%, the amount of lapis lazuli

3, 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 theoretical amount, in addition to the amount of barium dosage control in theory of 20 ~ 50%, and can be used in addition to the barium chromate or potassium chromate sodium or potassium dichromate ammonium sulfate or sodium dichromate,

4, 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 for reaction process, in which ammonium hydroxide dosage control in 102 to 120% of the theoretical amount, the content of the saturated solution of ammonium bicarbonate in 102 to 120% of the theoretical amount.
