Fine artificial graphite powders can be cold compacted to give bodies of high density ( approximately 88% of theoretical), low permeability (B/sub 0/ approximately 10/sup -14/ cm/sup 2/), and reasonable strength. Such powders, after vacuum annealing, will not compact. Die-compacted powder has strongly anisotropic properties owing to a high degree of preferred orientation within the compact; this effect is less marked in hydrostatically compacted powder. Minor dimensional changes occur when compacts are annealed at 600 to 1000 deg C. The preparation of fuels by incorporation of fissile and fertile materials into graphite powder and cold compacting is described. (auth)
