Structure and properties of barium and calcium borosilicate glasses

Structure-property relationships of alkaline earth borosilicate glasses were determined using solid state NMR, the glass transition temperature and density. A sharing of alkaline earth oxide amongst the borate and silicate networks was observed and modelled. Density and Tg data were compared with the constructed models providing support to structural ideas. Comparisons to structure-property relations of alkali borosilicate glasses were also made
