Abstract

Spherical amorphous carbon particles of narrow size distribution ranging in diameter from 3 to 5 μm were obtained by thermal degradation of a poly (divinylbenzene) powder, consisting of ~ ̊ 8 μm spheres, in an inert atmosphere at 500°C. The polymer colloid was generated by an aerosol technique described earlier. The large specific surface area of the so prepared carbon particles (650 m 2 g −1) as compared to their geometric area (0.8 m 2 g −1) indicates a high degree of porosity.
