| contents | Zn x-1Cu xMn2O4 Spinels; Synthesis, Structural Characterization and Electrical Evaluation Francisco Méndez-Martínez Federico González Enrique Lima Pedro Bosch Heriberto Pfeiffer Multidisciplinaria (Ciencias Naturales y Exactas) XRD spinel Ceramic Varistor Impedance Spectroscopy This work presents the structural characterization and electrical evaluation of Zn x-1Cu xMn2O4 spinels, which are materials presented as secondary phases into the varistor ceramic systems. Samples were analyzed by X-ray diffraction, solid-state nuclear magnetic resonance, infrared spectroscopy, scanning electron microscopy and impedance spectroscopy. Although, the addition of copper to the ZnMn2O4 spinel did not produce morphological changes, the structure and electrical behaviors changed considerably. Structurally, copper addition induced the formation of partial inverse spinels, and its addition increases significantly the electrical conductivity. Therefore, the formation of Zn x-1Cu xMn2O4 spinels, as secondary phases into the varistor materials, may compromise significantly the varistor efficiency. 2010 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47516172002 en http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.1 Vol.54 |
