Abstract
Thermal studies (at up to ~1500 ° C) carried out on some ytterbium sulphides in air or under nitrogen show that complex decomposition processes undergone before the ultimate formation of the ytterbium oxide. The decompositions take place as overlapping and incomplete reactions to give mixtures of various intermediates, such as Yb2O2S and Yb2O2SO4. Electron microscopy diffraction studies on the intermediate Yb2O2SO4 reveals a complex microstructure because of intergrowth with small precipitates of cubic phase Yb2O3.
