Abstract
The method of EMF measurement of a galvanic cell with solid electrolyte (EMF method) has been used for examination of the equilibrium conditions of wustite and spinel solutions in the Fe-Ge-O system in the temperature range of Т = 1100÷1300 K. X-ray diffraction and micro X-ray spectral methods were used for determination of phase composition. It is found that magnetite and iron germanate are restrictedly dissolved in each other. Isothermal sections of the phase diagram of the Fe–Fe3O4–Fe2GeO4 system are plotted at Т = 1273 and 1173 K.
