Radial Distribution Study of Vitreous Barium Borate

X-ray diffraction, radial distribution studies of a 20 percent barium oxide, 80 percent B₂O₃ glass have been performed using both the atomic and electronic distribution functions. From these distributions, the average barium-barium distance has been determined as 6.76 A. This distance is in good agreement with that predicted by Levin and Block on the basis of a structural interpretation of immiscibility data.
