Influence of Antimony Substitution on Spontaneous Strain and Thermodynamic Stability of Lanthanum Orthoniobate

Abstrakt

The analysis of the antimony substitution influence on temperature dependence of unit cell distortion has been done. The values of spontaneous strain and Landau order parameter for three different antimony contents varied had been calculated. The phase transition occurring for antimony substituted lanthanum orthoniobate was found to be second order. The high temperature solution calorimetry method has been used to investigate the influence of antimony substitution on stability of both monoclinic and tetragonal phases of antimony substituted lanthanum orthoniobate. It has been found that antimony substitution does not influence the stability of monoclinic phase. The average value of enthalpy of formation of antimony substituted lanthanum orthoniobate with fergusonite structure has been found to be equal to -132.0 ± 0.8 kJ/mol, while in the case of scheelite structure -126.4 ± 1.5 kJ/mol.
