ABSTRACT:
This invention relates to a method for the preparation of improved tiles or plates of enhanced density, freedom from defects, chemical and mechanical resistance, and increased longevity in service, for use as aluminum-wettable cathode surfaces for aluminum reduction cells. A mixture of Refractory Hard Material, carbonaceous filler, carbonaceous additive, and thermosetting binder system is subjected to vacuum during mixing so as to achieve a specified penetration depth as measured by ASTM standard C 360-63. The mixed composition is then molded, cured, and baked to form elements of the desired configuration.
