晶形助长剂对磷石膏制硫酸钙晶须性能的影响

Abstract

Abstract: Influence of crystal growing agent on growth behavior of calcium sulfate whisker，which was prepared by hydrothermal 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.

Key words: phosphogypsum, calcium sulfate whisker, crystal growing agent
