The NMR method has been successfully used in the study of the structure of oxide glasses and in lithium glasses. Using steady-state and pulse methods of B-11 and F-19 NMR, the authors have studied borate glasses in the PbO-B/sub 2/O/sub 3/-PbF/sub 2/-AlF/sub 3/ system. Lead fluoride was added to the composition of the experimental glasses. A small amount of PbF2 has a weak effect on the electrical conductivity, and it is only in the specimen with the maximum values of the PbF/sub 2/ concentration that conductivity becomes significant. In glasses of the PbO X B/sub 2/O/sub 3/ X AlF/sub 3/ compositions, there is an exchange of the oxygen and fluoride modifier anions and as a result the F ions are incorporated into the first coordination sphere of the lead cations.
