Popis:	The optimization of thermodynamic parameters in the Li2O–Al2O3 system using available thermodynamic and assessed phase diagram data is discussed. A procedure for obtaining a suitable associate species solution model for the liquid in this system is presented. It is shown that if the eutectic near the pure alumina composition is ignored during the optimization, the optimized thermodynamic parameters in this system result in a phase diagram that is in reasonable agreement with the experimental one. Optimized thermodynamic parameters for the associate species in the associate species liquid model and the solids in this system are provided. An optimized associate-regular solution model with a reduced number of associates in the liquid is also provided as a comparison.
