摘　　要：借助X射线衍射、扫描电子显微镜等分析方法,研究了晶形助长剂对以磷石膏为原料水热法制备硫酸钙晶须生长行为的影响。结果表明,以磷石膏为原料制备硫酸钙晶须适宜的晶形助长剂为氯化镁(掺量为磷石膏质量的1.0%),其次为十二烷基磺酸钠,效果最差的是硫酸铝。Influence of crystal growing agent on growth behavior of calcium sulfate whisker,which was prepared byhydrothermal method with phosphogypsum as raw material,was studied and analyzed by means of XRD and SEM etc..Results showed that when the calcium sulfate whisker was prepared from phosphogypsum,the proper crystal growing agent was magnesium chloride （doping amount was 1.0% of phosphogypsum）.The next-proper crystal growing agent was sodium dodecyl sulfonate and the worst was aluminum sulfate.
