Comparisons of self-diffusion coefficients of oxygen and viscosities. (a) Comparison of diffusion coefficients of oxygen MgSiO₃ bulk liquid with other molecular dynamics studies. Closed squares indicate our study, and purple, green, and blue open squares indicate the data of forsterite liquid from de Koker et al. ( 2009), Adjaoud et al. ( 2011), and enstatite liquid by Lacks et al. ( 2007), respectively. (b) Comparison of calculated viscosities with experimental results. The experimental data are taken from Bockris et al. ( 1955). Viscosities are calculated using the Einstein-Stokes relation and the effective radius reported by Lacks et al. ( 2007).
