Evaluación de aditivos para la fabricación de pastillas cerámicas
(Ingeniería de ProcesosEscuela de Ingeniería. Departamento de Ingeniería Procesos, 2006-11)
The development of this project consisted in the manufacturing of zinc oxide pieces for varistors evaluating different kinds of binders and at the same time it allowed to set the optimum conditions of the process concerning ...
Qualitative evaluation of active potential barriers in SnO2-based polycrystalline devices by electrostatic force microscopy
(Springer, 2007-06-01)
This paper discuss the qualitative use of electrostatic force microscopy to study the grain boundary active potential barrier present in dense SnO2-based polycrystalline semiconductors. The effect of heat treatment under ...
The dielectric suppress and the control of semiconductor non-Ohmic feature of CaCu3Ti4O12 by means of tin doping
(American Institute of Physics (AIP), 2011-03-28)
In this work it was demonstrated that the addition of Sn on CaCu3Ti4O12 material improved non-Ohmic behavior by suppressing dielectric properties. It was noted that the improvement of the varistor characteristics, monitored ...
Sintering of tin oxide using zinc oxide as a densification aid
(Kluwer Academic Publ, 2004-09-15)
The physicochemical electronic characteristics of SnO2 render it useful in many technical applications, including ceramic varistors, stable electrodes used in electric glass-melting furnaces and electrometallurgy of aluminum, ...
