摘　　要：对-45μm、-20μm以及-10μm超细鳞片石墨进行了酸化试验研究,通过优化试验条件使3种粒级的超细鳞片石墨的膨胀容积分别达到33.6mL/g、19.3mL/g和8.5mL/g。研究结果表明,超细天然石墨具有明显的插层效果。本试验研究结果可为拓宽超细石墨的应用提供一定的初步研究基础。Three ultrafine flake graphite samples with different particle sizes, -45 μm and -20 μm and -10 μm, were intercalated with H2SO4- HNO3 method. By optimizing the experimental conditions, the expansion ratios of three uhrafine flake graphite samples are 33.6 mL/g, 19. 3 mL/g and 8.5 mL/g, respectively, suggesting these ultrafine flake graphite samples have a certain effect of intercalation. The research results may contribute to broaden the application of ultrafine graphite and eryptocrystalline graphite.
