Abstract

A mixed B-site double perovskite ceramic, Na2(Mn0.5Ti0.5)WO6, was synthesised via a conventional solid-state route and comprehensively examined for its structural, microstructural, dielectric, impedance, and thermistor properties. X-ray diffraction analysis confirmed that the ceramic exhibits a dual-phase crystal structure. FESEM imaging revealed densely packed agglomerated grains with an average size of ~220 nm, while EDX confirmed the homogeneous distribution of Na, Mn, Ti, W, and O without extraneous impurities. Dielectric studies showed strong frequency-dependent dispersion and an increase in permittivity with temperature, attributed to Maxwell–Wagner interfacial polarisation and thermally activated defect dynamics. Impedance spectroscopy demonstrated non-Debye relaxation and revealed that the grain- and grain-boundary-related contributions evolve with temperature, consistent with a transition from (CQR) to (CQR)(CR) circuit behaviour. Measurements of resistance that depend on temperature showed a clear negative-temperature-coefficient (NTC) thermistor response that was caused by small-polaron hopping and conduction through oxygen vacancies. The results taken together show that the ceramic is a good choice for use in electronics and high-temperature sensing.
