Abstract
Calcium Titanium Oxide or Calcium Titanate (CaTiO3-CT) and Zinc doped calcium titanium oxide (Ca1-xZnxTiO3-CT:Zn) Powder in a concentration of (0 molar ration of Zinc) were obtained by a simple method called solid-state reaction. Ceramics are based on CaTiO3-CT and (Ca0.5Zn0.5) TiO3 solid solutions synthesized and characterized in order to study microwave dielectric properties. X-ray spectra analysis, FT-IR Spectra, and SEM studies shown that the synthesized powders were contained nano-crystallite shape are Orthorhombic. The suitable shift in the XRD peaks for x=0.5 composition towards comparatively lower angles gradually with the increase of “x” values, which indicates that the lattice parameters of Ca1-xZnxTiO3 decreases after substituting. The SEM produces the images of (CaTiO3-CT) and (Ca0.5Zn0.5) TiO3 by scanning the surface with a focused beam of electrons. The common grain size for x=0.5 has the highest value equal to 2.08 µm, and usually, the grain size has an increasing trend by increasing zinc content from 1.214 to 2.08 µm. In Fourier Transform Infrared Radiation spectroscopy (FTIR), IR radiations pass through the (CaTiO3-CT) and (Ca0.5Zn0.5)TiO3, which determine the quality consistency of the above mention samples. It can also identify the unknown materials and determine the number of components in a given mixture. The dielectric properties of the samples CaTiO3-CT and Ca1-xZnxTiO3-CT:Zn were studied at room temperature. The dielectric constant (εr) is found to decrease with an increasing frequency range from 2 to 2.50.
