Abstract:
Modified graphite particles derived from scaly natural graphite particles, characterized in that said modified particles satisfy all of the following requirements (a) to (c):(a) that the degree of circularity should be not less than 0.86;(b) that, upon microscopic observation, the broken-out section should show an appearance with graphite slices taking various directions;and (c) that, upon X ray diffraction, the peak intensity ratio (Ih.sub.110 /Ih.sub.002) between the 002 face (parallel to graphite layers) and 110 face (perpendicular to graphite layers), which serves as an index of the randomness of orientation, should be not less than 0.0050.
