The present invention provides a method of making a carbon electrode,
suitable for use as an anode in an aluminum reduction cell, which
comprises mixing an aggregate, comprising a mixture of particulate shot
coke, and a particulate carbonaceous material other than shot coke with
coal tar pitch or petroleum pitch or a combination of these pitches at an
elevated temperature to form a paste wherein said aggregate comprises a
combination of butts, coarse, and fine particles and said particulate
shot coke may comprise a majority of said coarse particles or fine
particles, and said paste comprises from about 80 to about 90%, by
weight, of said aggregate and from about 10 to about 20%, by weight, of
said pitch; forming said paste into a solid body; and baking said solid
body at an elevated temperature to form said carbon electrode.
