The direct reaction calorimetric method was used for the determination of the formation enthalpy of alloys which concentrations correspond to the: Ga₇Li₂, Ga₉Li₅, GaLi, Ga₄Li₅, Ga₂Li₃, and GaLi₂ intermetallic phases. The obtained experimental values of the formation enthalpy were: –18.1 ±0.8 kJ/mol at., –26.5 ±0.3 kJ/mol at., –34.7 ±0.3 kJ/mol at., –33.5 ±0.5 kJ/mol at., –32.8 ±0.3 kJ/mol at. and –24.6 ±1.4 kJ/mol at., respectively. After the calorimetric measurements, all the samples were checked by way of X-ray diffraction investigations to confirm the structure of the measured alloys. All the measured values of the formation enthalpy of the Ga-Li alloys were compared with literature data and the data calculated with use of the Miedema model.
