Abstract

PROCEDIMIENTO DE OBTENCION DE CERAMICAS SUPERCONDUCTORAS TEXTURADAS DE TRBA2CU3O, DONDE TR SIGNIFICA TIERRA RARA O YTRIO, MEDIANTE SOLIDIFICACION DIRECCIONAL. PROCEDIMIENTO DE SOLIDIFICACION DIRECCIONAL DE CERAMICAS PRESINTERIZADAS DE MATRIZ TRBA2CU3O7 EN LAS QUE SE HA MEZCLADO DE FORMA HOMOGENEA UNA CANTIDAD ADICIONAL DE TR2BACUO5 Y CEO2. TRAS LA FUSION INCONGRUENTE DE LA MEZCLA, SE OBTIENE POR REACCION PERITECTICA Y SOLIDIFICACION DIRECCIONAL BARRAS Y LINGOTES TEXTURADOS SUPERCONDUCTORES CON BUENAS PROPIEDADES MECANICAS Y CORRIENTES CRITICAS SUPERIORES A 1X106 A/CM2 A 5K Y 1X105 A/CM2 A 77K EN CAMPO MAGNETICO NULO. EL USO DE ADITIVOS COMO CEO2 PERMITE CONTROLAR EL PROCESO DE CRISTALIZACION DIRECCIONAL DEBIDO A SU INFLUENCIA EN LAS CARACTERISTICAS DE LA MEZCLA SEMISOLIDA A ALTA TEMPERATURA. AL MISMO TIEMPO LAS CARACTERISTICAS MICROESTRUCTURALES FINALES DE LA CERAMICA TEXTURADA SE VEN MODIFICADAS EN GRAN MEDIDA MEDIANTE EL USO DE DICHOS ADITIVOS.
