Abstract
PARA TRATAR CON SILICIO CUERPOS MODELADOS POROSOS DE CARBURO DE SILICIO/CARBONO SE TRANSFORMA UNA MEZCLA DE POLVO DE CARBURO DE SILICIO, AGLOMERANTE ORGANICO Y EVENTUALMENTE CARBONO EN UN CUERPO VIRGEN, SE ELIMINA EL AGLOMERANTE DEL CUERPO VIRGEN EN UNA ATMOSFERA NO OXIDANTE POR COQUIZACION A 1000 C APROXIMADAMENTE Y EL MATERIAL BRUTO OBTENIDO SE TRATA CON SILICIO FUNDIDO. EL MATERIAL BRUTO OBTENIDO DESCANSA SOBRE UN SOPORTE DE SISIC POROSO, QUE SE HALLA EN CONTACTO CON EL SILICIO LIQUIDO CON SU SUPERFICIE INFERIOR. EL CONJUNTO FORMADO POR EL SOPORTE DE SISIC Y EL CUERPO MODELADO OBTENIDO SE ENFRIA DESPUES DEL TRATAMIENTO CON SILICIO . COMO SOPORTE SE UTILIZA UN PAQUETE DE ANILLOS DE SISIC POROSOS, QUE SE DISPONEN PARALELOS ENTRE SI Y PERPENDICULARES A UNA PLACA DE COCCION DE GRAFITO RECUBIERTA CON SILICIO E IMPERMEABLE AL SILICIO LIQUIDO.
