Property characterisation of the extended lithium bismuthate glass system

In this paper we present a property characterisation of the extended lithiu m bismuthate system. These novel glasses made by rapid seller quenching, we re made over the extended range of x=0.20 to x=0.92 where x is the molar fr action of lithium present in the glass. A small glass forming gap,vas foun d between x=0.46 and x=0.54. The thermal stability, glass transition temper ature (T-g), density and shout wavelength optical cutoff were measured for each glass. We report that these glasses retain a large amount of carbon di oxide past x=0.66 in the form of lithium carbonate and a zeroth order empir ical model was effective in describing this behaviour The measured density trend was then analysed in terms of the retention of carbon dioxide using a simple mixing model. We also report on ternary glasses containing LiCl and LiF and the effects of adding these salts on the T-g.
