Abstract
PARA LA FABRICACION DE CUERPOS MODELADOS DE CARBURO DE SILICIO INFILTRADO CON SILICIO, EN ESPECIAL TUBOS, SE TRANSFORMA UNA MEZCLA DE POLVO DE CARBURO DE SILICIO, AGLOMERANTE ORGANICO Y EVENTUALMENTE CARBONO EN UN CUERPO VIRGEN ALARGADO CON FORMA CILINDRICA, SE ELIMINA EL AGLOMERANTE DEL CUERPO VIRGEN EN UNA ATMOSFERA NO OXIDANTE POR COQUIZACION A 1000 C APROXIMADAMENTE Y EL CUERPO BRUTO OBTENIDO SE TRATA CON SILICIO POR MEDIO DE LA ACCION DE SILICIO LIQUIDO CON TEMPERATURAS DE, AL MENOS, 1400 C. DURANTE EL TRATAMIENTO CON SILICIO DESCANSA EL CUERPO BRUTO SOBRE UN SOPORTE POROSO DE SISIC, QUE SE HALLA EN CONTACTO CON EL SILICIO LIQUIDO. EL SOPORTE DE SISIC POSEE UN CANAL RECTO CON SECCION TRANSVERSAL EN ANGULO Y CAVIDADES EN LAS QUE SE COLOCA EL CUERPO BRUTO CON FORMA DE CILINDRO A TRATAR CON SILICIO. EL SOPORTE DE SISIC POSEE PAREDES LATERALES, QUE SOBRESALEN HACIA ABAJO Y QUE SE HALLAN EN CONTACTO CON EL SILICIO LIQUIDO EN SU LADO INFERIOR.
