Abstract
Procedimiento para fabricar un superconductor macizo de cerámica de óxidos, formado por los elementos bismuto, estroncio, calcio, cobre y oxígeno y constituido esencialmente por cristales estirados, formados y dispuestos paralelamente entre sí, caracterizado porque se mezcla un super conductor en polvo, que contiene cobre en la red, con 0,04 hasta 0,5, con preferencia de 0,042 a 0,44 moles deCuF2 o fluoruro potásico por 100 g de cobre del superconductor, conformando la mezcla a una presión mínima de 1 MPa para obtener una pieza moldeada, que se calienta durante al menos 5 horas a 980 hasta 1.200 C, especialmente entre 1.000 y 1.050 C.
