Structural and thermal properties are reported for a range of caesiurn oxide-containing alkali borosilicate glasses, of the form xCS(2)O(100-x)ZMW (0 < X < 10), where ZMW represents a variety of simulated base-glasses. Glass densities increase and glass transition temperatures decrease with increase in caesium oxide concentration. Mass-loss from the melt is found to depend on composition in the same manner as the fraction of silicon Q(3) units, resolved from Si-29 MAS NMR, and is related to the presence of danburite medium-range order units, resolved from B-11 MAS NMR. Volatilization is shown to occur even in the absence of caesium oxide and the mixed alkali borosilicate composition of the volatile species, evolved from the melt at high temperature, is independent of the starting composition of the glass.
