This work presents a molecular dynamics simulation of CaSiO3 glass using Born–Mayer–Huggins potentials. The structural organization and structural phase transition under compression as well as network structure of CaSiO3 are clarified through analysis and visualization of molecular dynamics simulation data. The short-range order structure, intermediate-range order structure and the degree of polymerization of SiOx-network are also discussed in detail.
