爆轰裂解可膨胀石墨制备石墨微粉(英文)

A method to produce graphite micro-powder by detonation was provided and the detonated powder was characterized by XRD, SEM and nitrogen adsorption. Results indicated that the particle size of the detonated expandable graphite powder were in the range of 1 to 10μm, the BET specific surface area increased from 8.096 to 47.48m2/g, while the crystal parameters and flake-like morphologies changed little. Detonation offered a more convenient, quick and energy-saving method to make micrometer-sized graphite powder.
