Abstrakt: The cation distribution in magnesioferrite MgFe2O4was investigated using a “piston-cylinder” apparatus at three pressures (ambient, 1, and 2 GPa) over a temperature range of 600 to 1200 °C. Quenched samples of magnesioferrite were investigated by X-ray powder diffraction. The inversion parameter was derived from the unit-cell parameter at ambient temperature.
