"The solubility limits of iron oxide in solid lime were determined as a function of oxygen pressure at 1300º and 1400ºG in the system CaO-iron oxide. The stability region of dicalcium ferrite was determined with respect to formation of lime-iron oxide solid solution and liquid oxide. In addition, the hydration behavior in moist air of pure lime and sintered mixtures of lime and iron oxide was also observed. Pelletized samples were equilibrated under known oxygen partial pressures and quenched. Phases present in the quenched samples were identified by microscopy. The solubility limit of iron oxide in CaO is strongly dependent on the oxygen partial pressure, and decreases with increasing temperature. On the basis of these results, isothermal sections of the CaO-rich portion of the system CaO-iron oxide were constructed at 1300º and 1400ºC. Hydration tests on pure lime and CaO-iron oxide mixtures showed that lime containing iron oxide is more resistant to hydration than pure lime. The largest resistance to hydration was achieved by a lime solid solution saturated with iron oxide"--Abstract, page ii.
