摘　　要：为获得较为稳定的半水磷石膏,阻滞半水石膏在短时间内转化为二水石膏,研究了不同阻滞剂对半水磷石膏向二水磷石膏转化的效果。结果表明,筛选的阻滞剂对半水石膏的水合转化具有良好的阻滞效果。In order to get stable half-hydrate phosphogypsum, different inhibitors have been studied to inhibite conversion of half-hydrate phosphogypsum into dihydrate phosphogypsum in a short period. The re- suit inidieates that a inhibitor has high inhibiting effect on conversion of half-hydrate phosphogypsum into all- hydrate phosphogypsum.
