Ceramic Materials Type Scheelite: Properties and its Relations with Morphology and Dimension

Abstract

Advanced ceramic materials having properties for use in optical, electrical devices, catalysts, sensors, among other, are of great interest in research because these characteristics are necessary in multifunctional materials.Furthermore, recent studies demonstrate the strong dependence of the properties with the morphology and the particle size of ceramic materials. Gas sensor to SO2 and H2, based in SrMoO4, is more sensitive when employing the nanometric materials compared to micrometer.Research about process of formation of nanostructured compounds and with uniform morphology is required. For the advancement of science and technology, it are required the studies about the relation between the properties of the material and the synthesis methodology utilized in your manufacture and their possible technological applications. Therefore, it is in this way that the research project is directed.In general it is intended with the proposition of this project, which is continuity and deepening of previous research project, synthesize and characterize ceramic compounds of nanoscale structures in the form of powders and thin films, pure and hybrids with morphology control and homogeneity. Pure and doped ceramic compounds will be obtained using approximations of template-directed method via hydrothermal treatment assisted by microwave and complex polymerization method. The class of primary interest is the crystal-like structures "scheelite". The properties and possible applications will be investigated so that they can meet the needs of the consumer market in a short future. (AU)
