The pressure and temoerature dependences of the crystal structure and the physical properties of rutile have been calculated by means of MD simulations with a quantum correction. Interatomic potential functions of our model are composed of Coulomb, short range repulsion, van der Waals, and Morse interactions. The energy parameters were empirically determined to reproduce the fundamental properties of rutile. The MD results were compared with experimental data inthe literature and well reproduced the observed with experimental data in the literature and well reproduced the observed crystal structure and some physical properties including volume thermal expansivity and compressibility by using the present interatomic potential model.
