摘　　要：石墨复合导电材料是有陶瓷相和导电相构成,通过高铝矾土和钾基膨润土烧结成陶瓷相,由填充到陶瓷相之间的石墨导电链构成导电相。本文通过对比原材料烧结前后物相分析的结果,对石墨陶瓷复合导电材料烧结机理进行了探讨,结果表明:高铝矾土颗粒之间不会发生烧结,但在烧结过程中二次莫来石化要进行得更加完全;石墨颗粒之间会发生弱烧结,属于液相烧结。Graphite ceramic conductive composite material include ceramic and conductive phase composition. Through the high alumina and potassium bentonite sintered into ceramic phase, from filling the graphite conductive chain between the ceramic phase formed the conductive phase. In this paper, through contrast X-Ray diffraction analysis （XRD） results of the raw materials and after sintered materials, the sintering mechanism of graphite ceramic composite conductive material is discussed.
