Structural and Dielectric Properties of Rare earth Neodymium Zinc Titanite

Abstract

Using the high -resolution x-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), and temperature-dependent microwave resonator characterization the dielectric properties and phase assemblage of Rare earth Neodymium Zinc Titanite (NZT) was investigated in this research work. NZT ceramics samples were prepared via mixed oxide. The result shows that it is distrustful to be a stable perovskite structure, in fact something comparable to Ilmenite structure, nevertheless further research shows that the monoclinic structure can be purposed for NZT. The Modelling and simulation were used in this study to define the atomic position and structure of NZT. In conclusions, single-phase ceramics of NZT; have been synthesised at every sintering temperature 1250-1675°C. NZT has the temperature coefficient of resonant frequency 47 MK-1, Quality factor was 42000 at frequency of 4.33 GHz and relative permittivity 36. The crystal structure of NZT is monoclinic with Bravais Lattice P and space group of P21/n. Kikuchi line shows that this material has a single phase. These compositions have promising dielectric properties and can be used in microwave telecommunications.
