Abstract

The aim of the study was to investigate the solubility properties of the phosphogypsum a sideproduct of phosphor industry. Phase diagrams of potassium, calcium, hydrogen phosphates, sulphates and water are presented in order to determine equilibrium of solubility. Solid phases were investigated by X-ray diffraction, IR spectrometry and thermal analysis (DTG-DTA).
