In order to study the transport properties of ions and phase transformations in CaF2-MgF2-SiO2 molten salt system, this work provides extensive simulations from both molecular dynamics and CALPHAD approaches. The local structures, ionic self-diffusion coefficients, and viscosity of this system are investigated by classical interatomic potential molecular dynamics (IPMD) and first-principles molecular dynamics (FPMD). In addition, the thermodynamic database of CaF2-MgF2-SiO2 molten salt system is also established by using the CALPHAD approach and phase diagrams are predicted at different temperatures. All calculated properties are compared with experimental data from existing literature.
