Resumen:
Equilibrium conditions of the wustite and spinel solutions in the Fe-Ge-O system in temperature range T = 1100-1300 K are investigated by measuring the emf of the galvanic element with solid electrolyte (the emf method). X-ray diffractometry and electron probe microanalysis were used to determine the phase composition. It is established that the iron magnetite and germanate are partially miscible in one another. The isothermal sections of the phase diagram of the Fe-Fe3O4-Fe2GeO4 system at T = 1273 K and 1173 K are constructed. © 2013 Allerton Press, Inc.
