Abstract
LA PRESENTE INVENCION ESTA RELACIONADA CON UN METODO DE PREPARACION REPRODUCIBLE DE POLVOS CERAMICOS SUPERCONDUCTORES DE YBASI2CUSI3OSIX (X > 6.85), BASADO EN LA FORMACION DE UNA BARBOTINA CERAMICA HOMOGENEA OBTENIDA POR COPRECIPITACION DE LOS HIDROXIDOS DE COBRE Y DE ITRIO EN UNA SUSPENSION ACUOSA DE BACOSI3 FORMANDO ASI, UNA MEZCLA DE ALTA ENERGIA SUPERFICIAL QUE, POR CALCINACION EN AIRE A UNA TEMPERATURA COMPRENDIDA ENTRE 850G Y 950G DURANTE 1 A 4 HORAS, REACCIONAN RAPIDAMENTE ENTRE SI DANDO COMO PRODUCTO FINAL DEL PROCESO UN POLVO CERAMICO CONSTITUIDO POR UNA SOLA FASE, YBASI2CUSI3OSIX CON ESTRUCTURA ORTORROMBICA Y CONTENIDO DE OXIGENO X> 6.85, QUE ES SUPERCONDUCTOR. ESTOS POLVOS CERAMICOS GRANULADOS Y COMPACTADOS CONDUCEN, MEDIANTE SINTERIZACION EN AIRE ENTRE 900G Y 1.000G DURANTE 2 A 8 HORAS A CUERPOS DENSOS (>96% DE LA DENSIDAD TEORICA) CON TEMPERATURAS DE TRANSICION SUPERCONDUCTORAS 84K<TSIC<92K, QUE PUEDEN SER APLICADOS COMO MATERIALES ESTRUCTURALES EN CIRCUITERIA ELECTRONICA.
