Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE PREPARACION DE TRIQUITAS DE CARBURO DE SILICIO POR REACCION, EN ATMOSFERA NO OXIDANTE A UNA TEMPERATURA AL MENOS IGUAL A 1300 GRADOS C, DE UNA CARGA CONSTITUIDA POR UNA MEZCLA DE NEGRO DE CARBONO Y POR UNA FUENTE DE OXIDO DE SILICIO, PROCEDIMIENTO SEGUN EL CUAL EL NEGRO DE CARBONO TIENE UNA TASA DE OXIDABILIDAD (MEDIDA POR CALENTAMIENTO AL AIRE DURANTE 30 MINUTOS A 600 GRADOS C) AL MENOS IGUAL A 85%, LA FUENTE DE OXIDO DE SILICIO TIENE UNA GRANULOMETRIA INFERIOR A 100 NM Y LA VELOCIDAD DE SUBIDA EN TEMPERATURA ENTRE 1300 Y 1600 GRADOS C ES INFERIOR A 3 GRADOS C -1 POR MINUTO SI SE OPERA EN ATMOSFERA ESTATICA, Y AL MENOS IGUAL A 25 GRADOS C MIN SI SE OPERA BAJO PERCOLACION DE GAS. SE EFECTUA EVENTUALMENTE UN DESCANSO DE 5 MIN A 5 H A 1600 GRADOS C. PREFERENTEMENTE SE INTRODUCE EN CARBONO EN LA MEZCLA DE REACCION, EN SOBRESTOQUIOMETRIA CON RELACION A LA SILICE. EL CARBONO EXCEDENTE SE ELIMINA, AL FINAL DE LA REACCION, POR OXIDACION AL AIRE AALREDEDOR DE 600 GRADOS C.
