Pentagonal shaped ZnTiO₃ ceramics for microwave dielectric applications

ZnTiO₃—pervoskite based ceramic compound, synthesized by ball-milling assisted sintering yielded pentagonal shaped particles with heterogeneous size distribution. Dielectric loss (tan δ) plot as a function of frequency with various potential shows a decreasing trend. The imaginary part and electric modulus plot show a flat response in the microwave regime, at room temperature, which is due to dipole–dipole interaction. This property indicates the suitability of the prepared ZnTiO₃ for microwave frequency applications.
