The structures of boron oxide and sodium borate glasses, simulated by a molecular dynamics (MD) method, were analyzed in detail in comparison with X-ray diffraction data. There is good agreement between the MD-calculated and observed s·i(s) and g(r) (PCF) curves for 0.25Na2O⋅0.75B2O3 and 0.33Na2O⋅0.67B2O3 glasses. It suggests that the structures of glasses satisfy the random network model. On the other hand, the MD-calculated g(r) curve for B2O3 glass agrees with that of B2O3 melt rather than that of glass.
