Abstract

PARA LA ELABORACION DE UN SUPERCONDUCTOR A ALTAS TEMPERATURAS DE COMPOSICION BI2(SR, CA)3CU2O8 + X CON UNA RELACION DEL ESTRONCIO CON EL CALCIO DE ENTRE 5:1 HASTA 2:1 Y UN VALOR PARA X ENTRE 0 Y 2, SE MEZCLA INTENSIVAMENTE EL OXIDO Y/O EL CARBONATO DE BISMUTO, ESTRONCIO, CALCIO Y COBRE EN PROPORCION ESTEQUIOMETRICA. LA MEZCLA SE CALIENTA A TEMPERATURAS ENTRE 870 HASTA 1.100 C, HASTA QUE SE PRODUCE UNA MEZCLA HOMOGENEA. SE VIERTE LA MEZCLA EN COQUILLAS Y SE LA DEJA ENDURECER. EL MATERIAL TOMADO DE LAS COQUILLAS SE MALEABILIZA ENTRE 6 Y 30 HORAS A ENTRE 780 HASTA 850 C. FINALMENTE SE TRATA EL MATERIAL MALEABILIZADO AL MENOS 6 HORAS A TEMPERATURAS DE ENTRE 600 Y 800 C EN UNA ATMOSFERA DE OXIGENO. AL MATERIAL SE LE PUEDE, ANTES DE LA MALEABILIZACION, DAR LAS DIMENSIONES DESEADAS MEDIANTE PROCEDIMIENTOS MECANICOS. LA FORMA Y DIMENSIONES DE LOS CUERPOS DE MOLDEA PUEDEN DETERMINARSE TAMBIEN POR LA FORMA Y DIMENSIONES DE LAS COQUILLAS EMPLEADAS EN LA ELABORACION DEL MATERIAL.
