Dielectric Studies of 0.5Ba0.8Ca0.2TiO3.0.5CaCu3Ti4O12 Nanoceramic Fabricated by Chemo-mechanical Process
Abstract: The present investigation is aimed toward investigate a straightforward, inexpensive, and environmentally friendly chemo-mechanical method for preparing high-dielectric materials, specifically 0.5Ba0.8Ca0.2TiO3.0.5CaCu3Ti4O12 (BCT-CCTO), by combining metal nitrate combustion with solid TiO2 powder and titanium isopropoxide, Ti (OR)4. The composite was prepared by the mixing of individual materials of Ba0.8Ca0.2TiO3 and CaCu3Ti4O12 through the chemo-mechanical method. Initially, 99% pure Ba (NO3)3, Cu (NO3)2∙3H2O, TiO2 and glycine were taken in their stoichiometry ratios. …

Synthesis and Dielectric Properties of CaCu3Ti4O12 Doped with La3+
Abstract: The effect La3+ doping on the structural and dielectric properties of CaCu3Ti4O12 (CCTO) is investigated, resulting in a compound of the type Ca1-xLaxCu3Ti4O12 (x = 0.00, 0.20 and 0.50). The compounds have been prepared by conventional solid state reaction. The Ca1-xLaxCu3Ti4O12 ceramics were characterized by X-ray diffraction, SEM techniques. The grain size and the grain boundary resistivity increased with the increase of doping percentages. Dielectric constant of the samples decreases …
