Abstract

UN METODO PARA PRODUCIR UN COMPONENTE DE UNA CELULA DE PRODUCCION DE ALUMINIO HECHO DE UN MATERIAL COMPUESTO DE BASE DE CARBONO, QUE CONTIENE (A) UN NITRURO, OXIDO, CARBURO, BORURO DE METAL DURO REFRACTARIO O MEZCLAS DE LOS MISMOS Y ALUMINIO, TITANIO, SILICIO Y ZIRCONIO, Y ALEACIONES Y COMPUESTOS DE LOS MISMOS. IMPLICA, PRECIPITAR PRIMERO UNA MEZCLA DE REACCION DE ALUMINIO, TITANIO, SILICIO O ZIRCONIO Y PRECURSORES QUE REACCIONAN PARA FORMAR UN COMPUESTO DE METAL DURO REFRACTARIO Y ADITIVOS Y RELLENOS OPCIONALES. LA MEZCLA DE REACCION ES MEZCLADO CON CARBONO EN MICROPARTICULAS EN UNA CANTIDAD DE 1 A 20 PARTES POR PESO DE CARBONO POR UNA PARTE DE PESO DE LA MEZCLA DE REACCION; Y CON UN AGLOMERANTE COLOIDAL QUE CONTIENE AL MENOS UN DE LOS SIGUIENTES: ALUMINIOS, CERIOS, YTRIOS, TORIOS, ZIRCONIOS, MAGNESIOS, LICIOS, Y SILICIOS COLOIDALES, EN UNA CANTIDAD PARA CUBRIR ENTERAMENTE LAS PARTICULAS DE CARBONO. LA MEZCLA RESULTANTE ES COMPACTADA, SECADA Y CALENTADA PARA INICIAR LA REACCION DE LA MEZCLA DE REACCION MEDIANTE LA REACCION MICROPIRETICA AUTOPROPAGANTE.
