This paper studies the influence of tempe Abstract rature on the microstructure and the phase transition process of the SiO2 bulk model. This bulk model is constructed with 3000 atoms (1000 Si atoms and 2000 O atoms) at temperatures 300K, 500K, 1000K, 1500K, 2000K, 2500K, 3000K and 3500K and at the pressure 0GPa by the Molecular Dynamics Simulation method with the van Beest-Kramer-van Santen (BKS) pair interaction potential and periodic boundary conditions. |
