Polyhedral connectivity in high lead silicate glasses
We have a long-established interest in the structural role of heavy-metal, lone-pair cations such as Pb in glasses. PbO can be incorporated to very high concentrations in oxide... -
The anomalous thallium borate anomaly
We have a continuing interest in the structural role of lone-pair cations in glasses. Thallium oxide behaves unusually in borate glasses, not only in terms of its own...
