Scientific paper

We use molecular dynamics to simulate the diffusion of oxygen in MgSiO3 perovskite, and to investigate its ionic conductivity. Perovskite, containing oxygen vacancies, is found to be a superionic conductor at temperatures and pressures typical of the lower mantle (2625 K and 100 GPa). The predicted ionic conductivity, of ~ 100 S m-1, is in excellent agreement with that inferred for the lower mantle. The dominant diffusion mechanism in our simulation is vacancy diffusion, although ring diffusion has also been observed.
