Absolute Pressure and Temperature Calibration to 6GPa and 1700 K

提出的研究将为高压岩石学家提供一种绝对压力-温度校准方法，可在整个研究界的实验室中使用。该方法是建立在精确确定气体活塞缸装置中若干相交平衡边界的基础上的。其他实验室的仪器在绝对温度和绝对压力下都是通过参考这些设备的平衡观察结果来精确确定pi的边界来校准的。所提出的研究将以1%的绝对压力和温度精度确定相平衡，压力在~1.5和3gpa之间，700和1600 (K)之间。

The method is based on the accurate determination of several intersecting equilibrium boundaries in a gas piston cylinder apparatus. Apparatus in other laboratories are calibrated, in both absolute temperature and pressure, by referring equilibrium observations in those devices to the PIs' accurately determined boundaries. The proposed research will determine phase equilibria with an absolute pressure and temperature accuracy of 1% at pressures between ~1.5 and 3 GPa and between 700 and 1600 (K.
