Studies on the Crystal Chemistry of Titanium, Vanadium and Molybdenum Oxides at Elevated Temperatures

摘要

The work reported in this document has been performed in continua-tion of X-ray studies previously conducted by members of this research group on the crystal chemistry at elevated temperatures of titanium, vanadium and molybdenum oxides.nThe atomic arrangement of the ordered phase Ti30 occurring within the solubility range of oxygen in a-titanium, has been determined.nA study has been made of structural and geometrical relations between the o-titanium oxide and several other phases.nAn analysis has been performed of the phase relations of the vanadium-oxygen system within the VO0.25-VO1.5 region at 800°C.nThe crystal structure of the high-temperature modification of Ti3O5 has been determined from single-crystal data registered at 175°C.
