Abstract—The possibility of calculating the thermodynamic properties of glass melts in the Cs₂O–B₂O₃–SiO₂
system with the use of the vacancy variant of the generalized lattice theory of associated solutions is demon-
strated. A comparison with the experimental thermodynamic functions previously determined by high-temper-
ature mass spectrometry shows that the calculations performed within this approach lead to reliable thermody-
namic functions for glass melts in the Cs₂O–B₂O₃–SiO₂ system.
