Abstract
POLVOS DE NITRURO DE SILICIO SI3NA OBTENIDOSPOR VIA DE REDUCCION CARBOTERMICA Y NITRURACION DE SILICE, UTILIZABLES ESPECIALMENTE PARA LA FABRICACION DE MATERIALES CERAMICOS, QUE PRESENTAN UNA SUPERFICIE ESPECIFICA DE 30 M2/G, POR LO MENOS. PROCEDIMIENTO DE FABRICACION DE ESTOS POLVOS, QUE COMPRENDE LAS ETAPAS SIGUIENTES: A) A PARTIR DE SILICE, DE UN AGLOMERANTE QUE GENERA CARBONO, COMO MUY TARDE, EN EL MOMENTO DE LA REACCION DE REDUCCION CARBOTERMICA Y, LLEGADO ELCASO, DE CARBONO COMPLEMENTARIO, FABRICACION DE GRANULADOS DE UN VOLUMEN DE PORO CONTROLADO; B) REACCION DE REDUCCION CARBOTERMICA DE LOS GRANULADOS OBTENIDOS EN A, EN PRESENCIA DE UNA ATMOSFERA QUE CONTIENE NITROGENO; C) DESCARBURACION; D) OBTENCION DE POLVOS.
