提出了一种名为Daphne 7474的压力传输介质，它在室温下在P(S)=3.7 GPa时固化。 P 值几乎随温度线性增加，在 100 摄氏度时最高可达 6.7 GPa。液态介质实现的高压允许更高的加压极限，从而确保理想的静水压力。我们展示了压力下的体积变化、夹紧活塞缸单元中从室温到液氦温度的压力降低、金刚石砧单元中的压力分布及其标准偏差，以及红外特性，这些可能对实验应用有用。 (C) 2008 年美国物理研究所。
A pressure transmitting medium named Daphne 7474, which solidifies at P(S)=3.7 GPa at room temperature, is presented. The value of P, increases almost linearly with temperature up to 6.7 GPa at 100 degrees C. The high pressure realized by a medium at the liquid state allows a higher limit of pressurization, which assures an ideal hydrostatic pressure. We show a volume change against pressure, pressure reduction from room to liquid helium temperature in a clamped piston cylinder cell, pressure distribution and its standard deviation in a diamond anvil cell, and infrared properties, which might be useful for experimental applications.
