Study on the Effect of the Phase Transition of Pyrophyllite on the Resistance of the Heating Graphite Tube in High Pressure Reaction Cell
-
摘要: 在高温高压实验中,发现叶蜡石相变过程引起旁热式合成腔的加热石墨管电阻异常变化现象。对这一现象的若干规律及与叶蜡石相变的内在联系,进行了测试研究。本实验现象为在高温高压过程中实时地观察与研究叶蜡石相变规律,提供了可能性。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 analyzed. The experiments make it possible to observe and study the law of the phase transition of pyrophyllite in the process of HTHP.
