چکیده انگلیسی
The monoclinical structure AZrNb2O8 (A = Zn, Co, Mg, Mn) ceramics were prepared by the conventional solid-state method. The crystalline structure refinement, chemical bond ionicity, lattice energy were carried out to investigate the correlations between the crystalline structure and microwave dielectric properties for AZrNb2O8 (A = Zn, Co, Mg, Mn) ceramics based on the complex bond theory. Variations in the dielectric constant (εr) were explained by the ionic polarizability of the compositions. The quality factor (Q Ã f) and temperature coefficient of resonant frequency (Ïf) were correlated with the packing fraction and B-site octahedral distortions (δ) in these compositions, respectively.159
