A process for preparing graphite articles is presented. In particular, the process
includes employing a particulate fraction comprising at least about 35 weight percent
coke, coal or combinations thereof having a diameter such that a major fraction
of it passes through a 0.25 mm to 25 mm mesh screen. The particulate fraction is
mixed with a liquid or solid pitch binder, to form a stock blend; the stock blend
is extruded to form a green stock; the green stock is baked to form a carbonized
stock; and the carbonized stock is graphitized. The stock blend further comprises
one or both of carbon fibers (advantageously added after mixing of the particulate
fraction and pitch has begun) and small particle size filler (advantageously added
as part of the particulate fraction).
