Abstract

Thermochemical and phase diagram data for the Ga-N system were assessed by employing the CALPHAD method. A consistent model representation of available thermodynamic properties agrees well with the critically evaluated experimental data. Thermodynamic extrapolation/interpolation of these data was applied to estimate the sublimation and melting characteristics of the GaN compound: at atmospheric pressure of nitrogen, gallium nitride sublimates incongruently by decomposing into nitrogen-rich gas and gallium-rich liquid, but can melt congruently at high nitrogen pressure (~4.9 GPa).
