Abstract

ELETRODOS úTEIS PARA ELETRóLISE DE SAL FUNDIDO DE óXIDO DE ALUMìNIO EM ALUMìNIO. A presente invenção refere-se a um método de fabricação de um eletrodo de carbono, adequado par uso como um anodo em uma cuba de redução de alumínio, cujo método consiste da mistura de um agregado, compreendendo uma mistura de coque de detonação particulado e um material carbonáceo particulado diferente do coque de detonação, com piche de alcatrão de hulha ou uma mistura desses piches, sob uma elevada temperatura para formar uma pasta, em que o dito agregado compreende uma mistura de matérias residuais, partículas grossa e partículas finas, e o dito coque de detonação particulado pode compreender a maioria das ditas partículas grossas ou partículas finas, e a dita pasta compreende cerca de 80 a cerca de 90% em peso do dito agregado e cerca de 10 a cerca de 20% em peso do dito piche; modelando a dita pasta em um corpo sólido; e realizando o cozimento do dito corpo sólido a uma elevada temperatura para formar o dito eletrodo de carbono.
