摘要

Titanium dioxide (TiO2) is an important high-pressure material, extensively employed in amplification electronics and geology. The basic thermodynamics of the dependence of the TiO2 pressure / melting temperature of TiO2 at 0 and 16 GPa are studied in this work. In a diamond anvil cell (DAC), evaporation temperatures at nine specific pressures were measured under laser heating. Our model demonstrates that melting temperature behaves nonlinearly with pressure, hence it sheds light on the knowledge of TiO2 under severe conditions as well as the theoretical predictions from the Srivastava-Pandey equation of state.
