Abstract

LA INVENCION CONCIERNE A UN SUPRACONDUCTOR DE ALTA TEMPERATURA COMPUESTO DE LOS OXIDOS DE BISMUTO, ESTRONCIO, CALCIO Y COBRE Y, DADO EL CASO, DE PLOMO DE LA COMPOSICION BI2-A+B+C PBA(SR, CA)3B-C CU2+D OX, CON A=0 HASTA 0,7;B + C = 0 HASTA 0,5; D = -0,1 HASTA 0,1; X = 7 HASTA 10 Y UNA RELACION DE SR : CA DE 2,8 : 1 HASTA 1 : 2,8, ASI COMO SULFATOS DE ESTRONCIO Y/O BARIO. ESTE SE PUEDE PRODUCIR PORQUE SE MEZCLAN INTERNAMENTE LOS OXIDOS DE BISMUTO, ESTRONCIO, CALCIO Y COBRE Y, DADO EL CASO, PLOMO CON LOS SULFATOS DE ESTRONCIO Y/O BARIO, PORQUE LA MEZCLA SE FUNDE MEDIANTE CALENTAMIENTO A TEMPERATURAS DE 870 HASTA 1300 (GRADOS) C, EN DONDE LOS CONTENIDOS SUPERIORES EN SULFATOS DE ESTRONCIO Y/O BARIO EXIGEN MAYORES TEMPERATURAS, QUE EL CALDO METALICO SE VIERTE EN COQUILLAS, Y ALLI SE LE DEJA ENDURECER LENTAMENTE, Y QUE LOS CUERPOS MOLDEADOS TOMADOS DE LAS COQUILLAS SE FUNDEN A TEMPERATURAS DE 700 HASTA 900 (GRADOS) C EN UNA ATMOSFERA CON CONTENIDO DE OXIGENO.
