摘要：

The phase transition from a simple rhombohedral to an fcc phase of C70 was examined under high temperature and high pressure. The phase boundary has a steep positive slope in the pressure-temperature phase diagram. X-ray diffraction lines from solid C70 disappeared at 1170 K and 0.9 GPa. This was assumed to be due to the decomposition of C70 molecules, because the recovered specimen showed evidence for sp3 single bonds of carbon atoms.
