Description

Graphical abstract: -- The effects of substituting different cations (Mn, Zn, Mg and Co) at the A-site of AZrNb2O8 compounds on structural parameters such as packing fraction and B-site octahedral distortion were studied using X-ray powder diffraction in conjunction with Rietveld refinement. Variations in the dielectric constant (εr) were explained by the ionic polarizability of the compositions. The quality factor (Q × f) and temperature coefficient of resonant frequency (τf) were correlated with the packing fraction and B-site octahedral distortions (δ) in these compositions, respectively
