Procedimiento de obtención de cintas, hilos o láminas superconductoras de Hg(1-x) Mx Ba(2-y) Sry Ca(n-1) Cun O(2n+2+δ) con substratos de base Ag

Abstract

Procedimiento de obtención de cintas, hilos o láminas superconductoras de Hg(1-x) Mx Ba(2-y) Sry Ca(n-1) Cun O(2n+2+δ) utilizando la Ag y sus aleaciones como soporte o substrato metálico, con las siguientes etapas: a) preparación de una mezcla homogénea del óxido mixto superconductor o de los óxidos precursores multifásicos correspondientes con un exceso de Hg, HgO, CaHgO2 u otra fuente de mercurio cuyo objetivo sea saturar la Ag en forma de amalgama; b) las reacciones simultáneas vapor-sólido producidas entre 700°C y 900°C para dar lugar a la formación, recristalización y conexión de los granos superconductores mientras que la reacción de amalgamación con la Ag transcurre paralelamente con el exceso de Hg (vapor); c) repetición del proceso b previa nueva deformación plástica de la lámina, cinta o hilos por prensado, laminado o trefilado para mejorar la textura del superconductor.
