Synthesis And Structural Characterization of the PR3-XEUXBA5CU8O18 System
This research describes the synthesis and characterization of the Pr3-XEuXBa5Cu8O18-δ system with modification levels (x = 0, 0.5, 1, 1.5, 2 and 2.5). The synthesis process was achieved by solid state reaction (SSR). Precursor oxides of Pr6O11, Eu2O3, BaO and CuO were used with purities up to 99.999...

| description | This research describes the synthesis and characterization of the Pr3-XEuXBa5Cu8O18-δ system with modification levels (x = 0, 0.5, 1, 1.5, 2 and 2.5). The synthesis process was achieved by solid state reaction (SSR). Precursor oxides of Pr6O11, Eu2O3, BaO and CuO were used with purities up to 99.999%. Calcination temperatures were handled at 850 ° C, sintering at 900 ° C and oxygenation at 910 ° C. The structural characterization was determined by X-ray diffraction (XRD). A structural analysis was carried out with Rietveld refinement, where the coexistence of two phases TR358 and TR123 was evidenced. The net parameters were obtained and a perovskite-orthorhombic crystal structure with spatial group Pmmm (47) was achieved. It was concluded that the increase of the X modification level with Eu in the Pr3-XEuXBa5Cu8O18-d system has a large impact on the percentage composition of the phases and structural parameters. The increase or decrease of the value of the net parameters in structure 358 and 123 is affected by the mixture of oxidation states of Pr with those of Eu, causing the cell size to change. |

Esta investigación describe la síntesis y caracterización del sistema Pr3-XEuXBa5Cu8O18-δ con niveles de modificación (x=0, 0.5, 1, 1.5, 2 y 2.5), mediante el método de síntesis de reacción de estado sólido. Se utilizaron óxidos precursores de Pr6O11, Eu2O3, BaO y CuO con purezas del (99.999 %). Se manejaron temperaturas de calcinación a 850 °C, sinterización a 900°C y oxigenación a 910 °C. La caracterización estructural se determinó por difracción de rayos X (DRX). Se hizo análisis estructural con refinamiento Rietveld en donde se evidencia la coexistencia de dos fases TR358 y TR123, se obtienen los parámetros de red y se logra una estructura cristalina tipo perovskita-ortorrómbica con grupo espacial Pmmm (47). Se concluyó que el aumento del nivel de modificación X con Eu en el sistema Pr3-XEuXBa5Cu8O18-δ tiene gran incidencia en la composición porcentual de las fases y en los parámetros estructurales. El aumento o la disminución del valor de los parámetros de red en la estructura 358 y 123 se ven afectada por la mezcla de estados de oxidación del Pr con los de Eu, originando el cambio del tamaño de la celda.
