Synthesis and Thermodynamic Properties of Thulium Titanate

Abstract

The temperature stages of crystallization process for thulium titanate of pyrochlore structural type during the heating of hydroxide precursor obtained by reverse precipitation have been studied by DSC/TG, XRD, and electron microscopy. Tm₂Ti₂O₇ has been measured in the temperature range 2–1870 K and thermodynamic functions at 0–1900 K and the Gibbs energy of formation from oxides and elements have been calculated based on smoothed heat capacity. The contribution of the Schottky anomaly at 20–320 K into heat capacity has been revealed.
