英文摘要	Phase relations and equation of state (EOS) of natural cinnabar (alpha-HgS) are investigated by high-pressure and high-temperature synchrotron x-ray powder diffraction. The unambiguous cinnabar-rocksalt structure phase boundaries are determined to be P(lower)(GPa) = 15.54 - 0.014T (degrees C) and P(upper)(GPa) = 23.84 - 0.014T (degrees C) at 300-623 K. With K' fixed at 4, we obtain K(0) = 37(4) GPa, (partial derivative K/partial derivative T)(P) = -0.025(2) GPaK(-1), and alpha(0) = 3.79(20) x 10(-5) K(-1) for the cinnabar phase of alpha-HgS. The (partial derivative K/partial derivative T)(P) and alpha(0) of cinnabar phase are obtained for the first time. A nearly isotropic compression of cinnabar phase is observed by linear regressions.
