Study on the physical chemical charecteristics and capability of phosphogysum as building raw materials

Chemical analysis,atomic absorption spectroscopy,X-ray diffraction, scanning electron microscopy and a laser apparatus for particle measurement were used for determination of phosphogysum on the chemical composition,radioactivity,crystal appearance,particle size distribution and impurity content such as phosphorus,fluorine,organic compound;the various physical and chemical index influenced on phosphogypsum use for building materials was analysised.The impurity content was determined after phosphogysum was disposed through different methods,then the capability of phosphogysum used as building materials was studied.Experitmental results show that the phosphogysum through disposing can be used as building materials.
