To investigate the possibility of AlN synthesis from Li3N and Al as source materials, a phase diagram of the Li3N-Al system was constructed by using calculation of the phase diagram (CALPHAD) method. Thermodynamic data of a ternary system was prepared on the basis of data of binary systems, which are Al-Li, Al-N and Li-N. In the present work, we newly incorporated thermodynamic data of Li3AlN2 into the system. Gibbs energy function of Li3AlN2 is described by a stoichiometric compound model and the parameter was determined to reproduce our experimental results. The calculated phase diagram was verified by differential thermal analysis (DTA). The calculated solution temperature of Li3AlN2 agreed with the DTA results and the validity was confirmed.
