| Abstract: | In this paper, the crystallization course of dihydrate calcium sulphate was studied in MSMPR crystallizer by using calcium phosphate solution, sulfuric acid and phosphoric acid. The effect of temperature, average residence time and density of sulphate acid were discussed on nucleation rate, growth rate and crystal shape. The crystallization course of dihydrate calcium sulphate affected by APA was also researched. |
