摘要：

Four different fractions of phosphogypsum were characterized by several analytical techniques. The size and shape of particles were determined by scanning electron microscopy. Analyses of infrared spectroscopy and X-ray diffraction have shown that these particles are mainly composed of calcium sulfate more or less hydrated. Calcination tests were carried out showed that treatment of these powders at 600 degrees C for one hour increase their initial britghtness to values high enough to be used as a filler in paper.
