Melting temperatures of CaSiO₃. The black line represents the melting temperatures calculated in this study, the crosses represent the experimental data by Gasparik et al. (1994), the blue circles by Shen and Lazor (1995), the orange squares by Zerr et al. (1997), and the dark gray dashed line represents the molecular dynamics simulation by Liu et al. (2010). The gray region is the stability region of CaSiO₃ perovskite at the melting temperatures (Gasparik et al. 1994)
