The binary system K2SO4CaSO4
January 1, 1965
The binary system K2SO4CaSO4 was studied by means of heating-cooling curves, differential thermal analysis, high-temperature quenching technique and by means of a heating stage mounted on an X-ray diffractometer. Compositions and quench products were identified optically and by X-ray. Limited solid solution of CaSO4 in K2SO4 was found. There is a eutectic at 875°C and 34 wt. per cent CaSO4. Calcium langbeinite melts incongruently at 1011°C. The melting-point of CaSO4 (1462°C) was determined by the quenching technique using sealed platinum tubes. The only intermediate crystalline phase found in the system is K2SO4·2CaSO4 (calcium langbeinite).
