| 摘 要： | 在压力为1.0～4.0 GPa、温度为873～1 223 K下采用Sarltron-1260阻抗/增益-相位阻抗谱分析仪测定了叶蜡石的电导率.实验结果表明,电导率与温度间的关系符合Arrenhius关系式;叶蜡石的脱水引起电导率的突然变化,使电导率急剧上升;脱水前,电导率随着压力增大而减小,其导电机制为电子导电;脱水后,电导率随着压力增大而增大,其导电机制为离子导电. |

| Abstract: | Electrical conductivities of pyrophyllite were measured by virtue of Sarltron-1260 frequency and phase impedance spectroscopic analyzer in situation of 1.0-4.0 GPa and 873-1 223 K. The experimental results indicate that the relationships between electrical conductivity and temperature fit Arrenhius equation connection. The pyrophyllite dehydration may lead to abrupt increase; Before dehydration, the electric conduction is electron when the electrical conductivity decreases with the pressure increase. While the electric conduction is ion when the electrical conductivity decreases with the pressure increase after the dehydration. |
| Keywords: | pyrophyllite high temperature and high pressure electrical conductivity dehydration effect |
