Abstract

Lithium borosulphate glasses have been prepared in three different series: (a) (42·5 −x)Li2O:57·5 B2O3:xLi2SO4; (b) 42·5Li2O: (57·5 −x)B2O3:xLi2SO4 and (c) 42·5Li2O:57·5B2O3:xLi2SO4. The glass transition temperature (T g) of these glasses has been analysed on the basis of the fraction of four coordinated boron which governs the glass structure. The analysis reveals that the addition of Li2SO4 in series (a) and (b) gives rise to increased value of N4 whereas, in series (c) it increases the number of non-bridging oxygens.
