It is found that the concentration of sulfuric acid in liquid and the reaction temperature are the most sensitive factors for this process. Increasing the ratio of solid to liquid is disadvantageous for growth of crystals even though it does not effect obviously for the rate of dehydration of FGD gypsum. On the other hand,the more closed to the neutral range of pH value the liquid is adjusted,the better stability of the α-form calcium sulfate hemihydrate appear,the more favorable for modification of crystal habit the process is made.

研究中发现pH值和盐溶液浓度是影响FGD石膏脱水速度最敏感的因素，固液比虽然对脱水速度影响不大，但固液比增大对晶体生长和习性改良不利。pH值愈接近中性范围，愈能增强α半水石膏结晶在液相中的稳定性，有利于结晶习性改良。
