Abstract
A composition of the products of interaction in the system (NaPO3)3-Fe under heating was studied by X-ray analysis and calculation of ΔG ○ T . Possible pathways of the formation of iron phosphides of different chemical composition and other co-products during heating of sodium and iron cyclotriphophate to 1000°C were described on the basis of thermodynamic and X-ray data. The conditions for obtaining individual types of iron phosphides Fe3P, Fe2P, and FeP by interaction of sodium cyclotriphophate with metallic iron under heating were found.
