The transpiration method was used to study the evaporation of Sb 2 O 3 from a glass melt with the composition 70SiO 2 ·15K 2 O·15CaO·MgO (in wt%) at 1200° to 1300°C. The glass contained about 0.9 wt% Sb 2 O 3 . Assuming the monomer Sb 2 O 3 is the species of evaporation, the saturation vapor pressures could be calculated with ΔH V =218±20 kJ·mol −1 and ΔS V =128±10 J·mol −1 ·K −1 .
