Thermodynamic Studies on Sr5Nb4O15

The SrO–Nb2O5 system, especially Sr5Nb4O15 compound is of interest for their use as an electroceramics. In this work, was synthesized by solid-state reaction and characterised XRD. Thermodynamic properties like heat capacity, enthalpy formation Gibbs energy have been measured. standard molar Sr5Nb4O15(s) determined using oxide melt solution high temperature calorimeter. Based on these experimental data, a self-consistent thermodynamic function also generated. This data essential the optimization synthesis conditions materials evaluation stability under appropriate technological operating conditions.
