Abstract
Graphite is produced by extruding, carbonizing and graphitizing a green stock produced by hot mixing a crushed carbonized product with a carbonaceous binder, e.g. pitch or resin, the carbonized product having a volatile content of less than 8% by weight and having been prepared by hot mixing crushed uncalcined coke and a carbonaceous binder, extruding the hot mixture and carbonizing, e.g. in a baking furnace, the final temperature of the carbonizable shaped stock during carbonization being substantially uniform throughout the volume of the stock and the uncalcined coke used to prepare the carbonizable shaped stock having a degree of fineness such as to provide in the graphite a with-the-grain coefficient of thermal expansion greater than 3.0 x 10-6/ DEG C. (20-100 DEG C.). The degree of fineness is preferably such that at least 98% by weight of the coke will pass through a 200 mesh Tyler screen. The final temperature differential of the carbonized product formed from the carbonizable shaped stock is preferably not greater than 50 DEG C. The uncalcined coke may be a pitch petroleum, or other residue coke. Examples show a variety of suitable temperatures at which the various steps may be carried out.
