ABSTRACT: The present study explores the mixing properties of the Ca(SO4,HPO4)·2H2O solid solution and the role of the “double-salt ” Ca2SO4HPO4·4H2O (ardealite) by means of precip-itation experiments carried out in a solution calorimeter at 25 °C. Moreover, the dehydration behavior of a number of solids with different compositions is studied by thermogravimetry and thermo-X-ray diffraction. The experimental results indicate the existence of two (sulfate-rich and phosphate-rich) ranges of solid solution that are separated by two miscibility gaps from a range around the midpoint (∼50 % molar) composition in which ardealite forms. On the phosphate-rich miscibility range, the structural (020) layers contract with the sulfate content, whereas t...
