Molecular dynamics modelling of the structure of barium silicate

The addition of barium to silicate glasses is of interest for applications such as radiation or thermal shielding. The barium silicate system, xBaO–(100 − x)SiO 2, has a glass forming region around x = 25–40. Phase separation occurs at the lower range of x and has been a focus of previous studies.
