Summary: Environment-friendly lead-free perovskites have attracted great interest in the scientific community. The synthesis of PbNb2O6 using the sol-gel auto-combustion method was reported, with Ca substituting Pb to reduce toxicity and improve energy storage capacity. XRD analysis confirmed the transformation of the composition from a rhombohedral phase to an orthorhombic phase with complete replacement of Pb by Ca. The presence of dual phases was observed depending on the relative concentrations of Pb and Ca. The crystallite size ranged from 26-53 nm. Platelet-like morphology was observed in Ca-free composition, while rod-like morphology appeared with increasing Ca concentration. Dielectric analysis showed that Ca substitution enhanced the dielectric constant of PbNb2O6 over a wide frequency range.
