Abstract

PRENSADO DE POLVOS CERAMICOS APLICABLE A LA FABRICACION DE PELLETS COMBUSTIBLES PARA REACTORES NUCLEARES. EL POLVO METALICO CONTENIENDO DIOXIDO DE URANIO ES COMPACTADO EN UNA MATRIZ EJERCIENDO PRESION HIDROSTATICA A TRAVES DE UN MEDIO FLUIDO QUE PENETRA POR LA MATRIZ, MIENTRAS QUE, AL MENOS EN UNO DE LOS EXTREMOS DE ESTA SE APLICA PRESION MECANICA SOBRE EL POLVO. LA MATRIZ, QUE VA INCLUIDA EN UN PRENSA, ESTA COMPUESTA DE CARBURO DE SILICIO SINTETIZADO POR REACCION HECHO EN PARTE PERMEABLE A LOS FLUIDOS MEDIANTE SEPRACION PARCIAL DE SU FASE DE SILICIO LIBRE CONTINUA.
