The Fe–Fe3P eutectic appears at 1075°C and 16 mol% P. Schreibersite (Fe3P) melts incongruently at 1250°C to produce barringerite (Fe2P) and liquid containing 23 mol% P. Barringerite (Fe2P) melts congruently at 1575°C. Maximum solid solution of P in metallic iron at 6 GPa is 5 mol%. As temperature increases to 1600°C, the P solubility in the metallic iron decreases to 0.5 mol%, whereas the P content in coexisting liquid decreases to 3 mol%. The composition of quenched phases from Fe–P melt coincides with the compositions of equilibrium phases at corresponding temperature.
