<p>A coating composition comprising Refractory Hard Material, thermosetting resinous binder, mix liquid, carbonaceous filler, and carbonaceous additive is cured at a temperature below about 250oC, and carbonized at a temperature insufficient to effect graphitization of said resinous binder, so as to produce an aluminum wettable cathode coating having Refractory Hard Material in a non-graphitized carbon matrix. </p> |
