Abstract

ELETRODOS úTEIS PARA ELETRóLISE DE SAL FUNDIDO DE óXIDO DE ALUMìNIO PARA ALUMìNIO. A presente invenção proporciona um método para fabricar um eletrodo de carbono, adequado para uso como um ânodo em uma célula de redução de alumínio, que compreende misturar um agregado, compreende uma mistura de coque por explosão particulado, e um material carbonáceo particulado em vez de coque por explosão com piche de alcatrão de carvão ou piche de petróleo ou uma combinação destes piches em uma temperatura elevada para formar uma pasta onde o dito agregado compreende uma combinação de partículas grossas, médias, e finas e o dito coque por explosão particulado pode compreender em sua maior parte as ditas partículas finas, e a dita pasta compreende a partir de cerca de 80 a cerca de 90%, em peso, de dito agregado e a partir de cerca de 10 a cerca de 20%, em peso, de dito piche; formar a dita pasta dentro de um corpo sólido; e assar o dito corpo sólido em uma temperatura elevada para formar o dito eletrodo de carbono.
