Caracterización de superconductores de alta temperatura crítica

Abstract

La superconductividad es un fenómeno que abarca desde efectos cuánticos a escala macroscópica hasta aplicaciones tecnológicas en campos tan diversos como la medicina, el transporte o la generación de energía. Dadas las posibilidades únicas de los materiales superconductores, pero también las fuertes limitaciones de estos, tanto en cuanto a su temperatura de operación como a su procesado, es necesario investigar en ellos para mejorar ambas condiciones. Partiendo de un compuesto derivado del superconductor de alta temperatura por excelencia, el YBaCuO, el dopaje por huecos del superconductor puede realizarse por diversos métodos de oxidación, entre los que se incluye la oxidación por vía electroquímica. Desde el punto de vista de la microestructura del material, se requiere una alta porosidad abierta para así maximizar el contacto electroquímico. En este proyecto se ha trabajado en la generación de un grado de porosidad óptimo empleando para ello varias composiciones de dos agentes formadores de poro: harina y grafito. Mediante la caracterización de propiedades fisicoquímicas, mecánicas y magnéticas, se pretende establecer un correcto procesado del material, que resulte en una mejora de las propiedades tras la oxidación electroquímica. Superconductivity is a phenomenon that ranges from quantum effects on a macroscopic scale to technological applications in fields as diverse as medicine, transport or power generation. Given the unique possibilities of superconductive materials, but also their strong limitations in terms of both operating temperature and processing, research is needed to improve both conditions. Starting from a compound derived from the high temperature superconductor par excellence, YBaCuO, hole doping in the superconductor can be carried out by various oxidation methods, including electrochemical oxidation. From the point of view of the microstructure of the material, a high open porosity is required to maximize electrochemical contact. In this project we have worked on the generation of an optimum degree of porosity using various compositions of two pore-forming agents: flour and graphite. By means of the characterization of physicochemical, mechanical and magnetic properties, it is intended to establish a correct processing of the material, which results in an improvement of the properties after the electrochemical oxidation.
