Abstract: 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 includes carbon fibers added after mixing of the particulate fraction and pitch has begun.

Abstract: A sealant useful for sealing the surfaces of carbon foams to provide a surface useful for, inter alia, composite tooling or other high temperature applications or for bonding of carbon foams together to form larger blocks.

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).

Abstract: A process for preparing pins for connecting carbon electrodes is presented. In particular, a process for preparing pins for connecting carbon electrodes including the steps of combining calcined coke, a liquid pitch binder and carbon fibers derived from mesophase pitch to form a pinstock blend; extruding the pinstock blend to form a green pinstock; baking the green pinstock to form a carbonized pinstock; and graphitizing the carbonized pinstock by maintaining the carbonized pinstock at a temperature of at least about 2500° C. for no more than about 18 hours is presented. The pins prepared by the inventive process are also presented.
