ABSTRACT:
To provide the spherical carbon particles having a novel structure different from the conventional carbon particles, uniform in shape, well dispersible in solvents and easy to handle.Spherical carbon particles of 5 nm to 100 μm in diameter having a void or voids enclosed by the carbon crystal wall, which particles have such a structure that the carbon crystal ends are exposed or the carbon net plane is looped at least at a part of the outer periphery of the particles, and an aggregate of spherical carbon particles of 5 nm to 100 μm in diameter having a void or voids enclosed by the carbon crystal wall, which aggregate has such a property that the ratio of the spherical carbon particles having a radial ratio in the range of 1.0 to 1.3 is not less than 40% by number.
