| Abstract: | Under high temperature and high pressure (HTHP),We find that the process of the phase transition of pyrophyllite causes abnormal change of the resistance of the graphite tube indirectly heating the reaction cell.Several laws of the phenomenon and the interior relations between the laws and the phase transition of pyrophyllite were analysed.The experiments make it possible to observe and study the law of the phase transition of pyrophyllite in the process of HTHP. |

| Keywords: | HTHP pyrophyllite phase transition graphite tube resistance |
