A graphite body comprises aligned graphite flakes bonded with a binder, in which the graphite has an average particle size of >200 μm.Methods of forming such highly oriented graphite material include:—a) forming a mixture of a mesophase pitch with a graphite powder;b) rolling the mixture to align the graphite powder and to form a body of graphite and pitch;c) carbonising the body; and optionallyd) graphitising the body.Pressing rather than rolling may be employed.Such graphite bodies have high thermal conductivity and anisotropy and may be used for thermal management.
