Inorganic Materials Aims and scope

Abstract

The crystal structure of the mineral creedite (hydrous calcium aluminum sulfate fluoride, Ca3Al2(F,OH)10(SO4) · 2H2O) has been determined by Rietveld powder diffraction analysis. X-ray diffraction data obtained in the temperature range from 25 to 470°C indicate that the crystal structure of creedite is stable up to 390°C. We have measured the unit-cell parameters of creedite as functions of temperature and determined its thermal expansion coefficients. Above 390°C, the mineral decomposes.
