摘　　要：用不同粒度（60～180目）的石墨在相同条件下制备可膨胀石墨和同一粒度的石墨在不同酸化条件下制备可膨胀石墨，通过差量法和元素分析对石墨酸化前后总质量及主要元素的量的变化，对粒度和不同酸化条件对可膨胀石墨层间化合物插入量的影响进行了分析。结果表明：插入量随酸化、氧化条件的增强而增加、随粒度的变化不明显。Expansible graphite was prepared using different granularity graphite（60 -180 mesh） in the same conditions, and using the graphite of 160mesh in different acidification conditions. The analysis of the change in the aggregate quantity of the graphite during the expansion was undertake by weight measure and IR--Spectrometric C/S Analyzer. The result of the influence of graphite granularity and the reaction conditions on the inserted quantity was attained that the inserted quantity increaing with the stonger of the reaction conditions and decreased with the dimishing of the graphte granularityl.
