The Li 2 O–B 2 O 3 quasi‐binary system is assessed. A two‐sublattice ionic solution model, (Li 1+ ) P (O 2− , BO 3 3− , B 4 O 7 2− , B 3 O 4.5 ) Q , is adopted to describe the liquid phase. All solid phases are treated as stoichiometric compounds. A set of parameters consistent with most of the available experimental data on phase diagram and thermodynamic properties is obtained by using the CALPHAD technique.
