considered as the most promising potential candidates for solid-state thermal energy
storage in the orientationally disordered high temperature phases. In this study, we first
propose a new PG-TRIS-NPG phase diagram based on experimental data of the three sub-
binary systems NPG-PG, PG-TRIS, and NPG-TRIS with CALPHAD methodology. The NPG-
PG binary phase diagram was optimized using sub-regular models that showed complete …
