Abstract
An electrode member comprising an electrode body having cementing pitch adhered to and impregnated within at least a portion of its electrode joint surface. Also a process for producing an electrode joint comprising applying a cement which is a solution/slurry of cementing pitch in nonaqueous organic solvent to at least a portion of the mating surfaces of such electrode joint.
Claims11
In an electrode member for incorporation into an electrode joint, which electrode member comprises at least one porous electrode body having at least one electrode joint surface adapted to be disposed in a mating relationship with a second electrode member:
- the improvement wherein cementing pitch is adhered to and impregnated within at least a portion of said at least one electrode joint surface, wherein said cementing pitch has a carbon yield of more than about 50 percent and includes pitch particles having an average diameter of less than about 0.003 inch.
An electrode joint comprising at least two porous electrode segments having mating end faces provided with threaded sockets and a threaded connecting pin screwed into each socket;
- characterized in that a cementing pitch is adhered to and impregnated within at least a portion of one of said end faces and said connecting pin, wherein said cementing pitch has a carbon yield of more than about 50 percent and includes pitch particles having an average diameter of less than about 0.003 inch.
