dc.description.abstract | En este trabajo se sintetizaron polvos cerámicos pertenecientes al sistema SnO2 –Bi2O3, a través de los métodos de precipitación y precursor polimérico (Pechini). Estos métodos permitieron obtener partículas nanométricas, con alta pureza química. Los polvos obtenidos se caracterizaron utilizando análisis térmico (ATD/TG), Difracción de Rayos X (DRX), distribución de tamaño de partícula y Microscopía Electrónica de Barrido (MEB). Con el fin de determinar su comportamiento como sensor, con los polvos sintetizados se conformaron películas gruesas sobre sustratos de alúmina a través de la técnica de “screen printing”. Se determinó la variación temporal de la resistencia eléctrica del sensor al cambiar la atmósfera de vacío a oxígeno o de vacío a monóxido de carbono. Se determinó la sensibilidad y estabilidad del sensor de gas. | spa |
dc.description.abstract | In this work, SnO2 –Bi2O3 ceramic powders were synthesized through precipitation and polymeric precursor (Pechini) methods. Through these methods, high purity nanometric particles were obtained. Powders were characterized through Simultaneous Gravimetric and Differential Thermal Analyses (DTA/TG), X-Ray Diffraction (XRD), particle size distribution and Scanning Electron Microscopy (SEM). Then, employing the synthesized powders thick films were conformed and their electrical behavior was determined. Time response of the sensor electrical resistance when the atmosphere is changed from vacuum to oxygen or to carbon monoxide was registered. Also, the sensitivity and stability of the sensor were determined. | eng |
