New Findings in the Area of Ceramics Reported from L. Singh and Colleagues [Dielectric, AC-impedance, modulus studies on 0.5BaTiO(3) center dot 0.5CaCu(3)Ti(4)O(12) nano-composite ceramic synthesized by one-pot, glycine-assisted nitrate-gel ...]

By a News Reporter-Staff News Editor at Journal of Technology -- Data detailed on Ceramics have been presented. According to news originating from Taejon, South Korea, by VerticalNews correspondents, research stated, "A nano-composite electro-ceramic with the chemical formula 0.5BaTiO(3) center dot 0.5CaCu(3)Ti(4)O(12) (BTO-CCTO) has been synthesized by a glycine-assisted nitrate-gel route which is simpler and faster at relatively low temperature than the conventional solid-state synthesis method. X-ray diffraction (XRD) analysis showed the existence of BTO as a secondary phase alongside the major phase of CCTO."

Our news journalists obtained a quote from the research, "Transmission electron microscope (TEM) analysis of the composite shows that nano-particles (60 +/- 15 urn) were obtained. Further, scanning electron microscope (SEM) images show that the morphology consists of a few large grains of CCTO (similar to 1-5 mu m) embedded in small grains of BTO (similar to 500 nm-1 mu m) with a bimodal distribution. The impedance analysis shows two major contributions associated with the grains and the grain boundaries."

According to the news editors, the research concluded: "Modulus analysis of this composite confirmed the presence of a Maxwell-Wagner type relaxation, which is temperature dependent The activation energy value was found to be 0.80 eV, and this composite is electrically conductive due to the mobility of the ionized oxygen defects."
