Pitch-carbon fiber binder, useful for making shaped carbon or graphite articles, particularly electrodes, has the fibers randomly dispersed as monofilaments

Preparation of a fiber-pitch binder (A) by dispersing carbon fibers (CF) in a pitch of viscosity 0.1-5 P, at CF content 0.5-10 wt.% on the pitch. Independent claims are also included for the following: (a) similar process in which CF (amount not specified) is dispersed in the pitch as essentially individual monofilaments having a random orientation in the mixture; (b) (A) comprising a pitch of viscosity 0.1-5 P at 140-260[deg]C and 0.5-10 wt.% CF, dispersed as in (a); (c) method for producing a shaped carbon article (B) by mixing (A) with a filler, then molding and carbonizing the mixture; (d) (B) that contains 1.5-3 wt.% CF, dispersed as in (a); (e) preparation of a shaped graphite article (C) with reduced coefficient of thermal expansion (CTE) by graphitization of (B); (f) (C) that includes CF at 1.5-3 wt.%, dispersed as in (a); and (g) (C) with longitudinal CTE of -0.5 to +0.10 X10->6>/[deg]C at 25-200[deg]C.
