摘要

摘要: 在金刚石压腔高压装置（DAC）上，采用外加温实验技术和同步辐射角度色散X射线衍射技术，在最高温度628 K和最高压力32.0 GPa条件下，对天然黄铜矿进行了相变及热状态方程研究。实验样品在约6.0 GPa条件下发生了Chalcopyrite-Rocksalt相变。获得了天然黄铜矿的高温高压实验数据，并根据二阶Birch-Murnaghan状态方程，对所获得的实验数据进行了状态方程拟合，首次获得了天然黄铜矿Rocksalt相的体弹模量K0＝109(3) GPa，体弹模量的温度导数(dK/dT)p=-0.033(4) GPaK-1和热膨胀系数0=2.0(2)10-5 K-1。

Abstract: In situ angle dispersive X-ray diffraction measurements for a natural chalcopyrite were performed by using heating diamond anvil cell instrument with synchrotron radiation at BSRF up to 32.0 GPa and 628 K. The phase transition of chalcopyrite from chalcopyrite structure to rocksalt structure is around 6.0 GPa. A fit to the high temperature third-order Birch-Murnaghan equation of state yielded an isothermal bulk modulus K0＝109(3) GPa, a temperature derivative of the bulk modulus (dK/dT)p=-0.033(4) GPaK-1, and a thermal expansion coefficient 0=2.0(2)10-5 K-1 of rocksalt structure phase of chalcopyrite for the first time.
