摘　　要：以脱硫石膏为原料,利用水热法合成了α型半水石膏晶须.研究结果表明,以十二烷基磺酸钠为转晶剂,在120℃条件下反应10 h,可获得较优异的微米级的α型半水石膏产品,研究结果对脱硫石膏的综合利用以及微米级石膏晶须的工业化生产具有一定的指导意义.α-hemihydrate gypsum whisker was prepared by hydrothermal synthesis method using gypsum from flue gas desulphurization（FGD gypsum） as raw material.The optimal conditions of the preparation of gypsum whiskers were that the reaction temperature was 120 ℃,crystal modifier was sodium lauryl sulfate,with the reaction time of 10 h.It is pointed out that the research is helpful for the production of α-hemihydrate gypsum whisker and the recirculation of FGD gypsum.
