Effect of structural transitions on the thermodynamic properties of NdMnO3 compound
It is established by thermal analysis and high-temperature X-ray diffractometry that the NdMnO3 compound undergoes an O°-O phase transformation in the temperature range of 620–800°C in air. The equilibrium oxygen pressure of the dissociation reaction of NdMnO3 compound is measured by the static method and the thermodynamic characteristics of the formation of NdMnO3 compound from elements are calculated.
