Abstract Scope A wide range of binary lead borate glasses (30 ≤ x ≤ 80 mol % PbO) were studied with Raman, 11B magic angle spinning nuclear magnetic resonance (NMR), and 207Pb static NMR. The 207Pb NMR anisotropic chemical shift interaction was analyzed using a new program that utilizes approximate Bayesian computations on the extended Czjzek model, which models glass disorder. Quantification of the boron environment from 11B MAS NMR through DMFit and semi-quantitative Raman analysis were also performed. This work finds 1) lead borate glasses with high lead concentrations approach structures similar to lead oxide crystals, 2) further evidence of the mixed role of lead as a network former and modifier, and 3) under-modification of the borate network.
