The Effect of Pressure Transmitting Medium on the High Pressure Experiments in Diamond Anvil Cell (DAC): Experimental Measurement of the Equation of State (EOS) of Pyrope
-
摘要: 采用氩气作传压介质测得的状态方程数据，在高压区，与酒精溶液作传压介质的情况极为不同。因此，对于高弹性模量材料，使用酒精溶液，不能有效地工作到超过20 GPa的范围。本文也比较了氩气压强规的使用情况。Abstract: The EOS data of pyrope in high pressure region measured in DAC technique by using Ar as pressure transmitting medium has been found to be different from that obtained by using methyl and ethyl alcohol mixture as pressure transmitting medium. It follows that in case of measuring the EOS data of materials with high value of modulus of elasticity, methyl and ethyl alcohol mixture cann't be used effectively as the transmitting medium in pressure region of exceeding 20 GPa. The utility of Ar high pressure scale hase been discussed.
