摘　　要：研究了结晶反应温度、时间、搅拌速度、表面活性剂对磷石膏中共晶磷含量的影响。实验条件下,共晶磷含量减少约70%。当产品磷酸质量分数32%时,共晶磷含量为0.5%。The influence of crystallization temperature, reaction time, stirring intensity,and crystal modifier on co-crystallized phosphorus content in phosphogypsum was studied emphatically. Under the experimental condition, the co-crystallized phosphorus content was reduced by about 70%, and it was 0.5%(P_2O_5) when the concentration of phosphoric acid solution was 32%(P_2O_5).
