According to the existing data, iron is a very efficient solvent for nitrogen. In this work, the results of first steps toward crystallization of GaN from Fe‐based solutions at 1 GPa N2 pressure are reported. Melting of Fe at 0.88 GPa N2 pressure is studied by differential thermal analysis (DTA) which shows a strong (≈200 °C) decrease of melting temperature as compared to the well‐established value of 1570 °C for pure Fe at 0.88 GPa at inert atmosphere. The N content of about 11.9 at.% is found by ON836 LECO analyzer in the Fe samples after DTA. It means that the observed drop of Tm (Fe) is related to the high solubility of nitrogen in Fe metal. Also the dissolution of GaN in Fe in 1370–1480 °C temperature range is studied. Encouragingly high (22–30 at.%) solubilities of Ga (direct measurement) and most probably, as high for N (evaluated from mass balance) are found.
