磷石膏理化特性对磷石膏库稳定性的影响

Study on the Impact of Physicochemical Characteristics of Phosphogypsum on the Stability of Phosphogypsum Dam

通过磷石膏理化特性和晶体结构测试,揭示了磷石膏具有在纯水和盐水中溶解度不一、并随着盐溶液浓度的变化其溶解度不断变化的特征,磷石膏晶体结构也具有这种特性,为磷石膏稳定性研究提供依据。

The solubility of phosphogypsum is dissimilar in pure water and salt water, and it changes along with the salinity change of water. Also the crystal structure of phosphorus gypsum will change along with the change of solution environment. The phosphorus gypsum in the dam often has this kind of transformation. This paper demonstrates this change through some experiments and tests of the crystal structure of phosphorus gypsum.
