However, these general potentials are not guaranteed to be applicable to the full composition range of glass systems. In addition, CMD with these potentials cannot generate boron superstructures such as the boroxol ring (three boron-membered ring with three-coordinated boron, B 3 ), which has been observed experimentally. This situation has improved with the recently developed BMP (Bertani, Marco, and Pedone) potentials, which can form structures including boroxol rings and simulate various oxide glass systems. Structural models based on the principle of charge compensation for alkali borate and borosilicate glasses have been established and used to predict the population of B 4 in alkali borate (DBX model) and alkali borosilicate
