Melting of CaSiO(3) Perovskite at High Pressure
Ab initio molecular dynamics simulations predict that CaSiO(3) perovskite melts at 5600 K at 136 GPa, and 6400 K at 300 GPa, significantly higher than MgSiO(3) perovskite. The entropy of melting (1.8 k(B) per atom) is much larger than that of many silicates at ambient pressure and of simple liquids...
