Abstract

POLVOS DE NITRUROS Y CARBUROS OBTENIDOS POR REDUCCION Y, LLEGADO EL CASO, POR NITRURACION DE OXIDOS METALICOS, UTILIZABLES ESPECIALMENTE PARA LA FABRICACION DE MATERIALES CERAMICOS Y QUE PRESENTAN UNA SUPERFICIE ESPECIFICA COMPRENDIDA ENTRE 30 Y 250 M2/G. PROCEDIMIENTO DE FABRICACION DE POLVOS QUE CONPRENDE LAS SIGUIENTES ETAPAS: A) FABRICACION DE GRANULADOS DE UN VOLUMEN DE PORO CONTROLADO, PARTIENDO DE OXIDO O DE OXIDOS METALICOS DE GRANULOMETRIA INFERIOR A 10 NM, DE UN AGLOMERANTE QUE GENERA CARBONO, LO MAS TARDE EN EL MOMENTO DE LA REACCION CARBOTERMICA Y, LLEGADO EL CASO, DE CARBONO COMPLEMENTARIO. B) REACCION DE REDUCCION CARBOTERMICA DE LOS GRANULADOS OBTENIDOS EN A, LLEGADO EL CASO, EN PRESENCIA DE UNA ATMOSFERA QUE CONTIENE NITROGENO. C) DESCARBURACION. D) OBTENCION DE LOS POLVOS.
