ABSTRACT:
In making carbon bodies for lining aluminum reduction cells, an aggregate including carbon recovered from used linings of such cells is mixed with binder material incorporating an alkaline-catalyzable furan binder. Residual contaminant material in the recovered carbon acts as a catalyst for the furan binder, so that the binder-aggregate mixture constitutes a self-hardening carbon lining body.
