Abstract: The enthalpies of fusion of both Li₂BeF₄ and Na₂BeF₄ were measured and the values of 41.9 and 25.5 kJ mol^-1, resp., were found. The equations for the partial enthalpy of mixing, partial excess Gibbs free energy, and partial excess entropy (in all cases at 1135 K) for the BeF₂ as well as for the LiF side were derived. The integral excess quantities of mixing for molten LiF-BeF₂ mixts. were calcd. The structural reasons for the obtained values of the studied thermodn. quantities were discussed.
