摘要：

The phase evolution during reaction sintering of stoichiometric mixtures of CaCO3/(6-x)Al2O3/ xFe(2)O(3) was investigated. The microstructural evolution as a function of iron content and firing temperature was also studied. It was found that the appearance during sintering of several intermediate phases (CA, CA, and CAF(2)) as well as the phase evolution during the Ca0.6(Al,Fe)(2)O-3 solid solution formulation and the final microstructures after sintering, call be explained by means of the CaO-Al2O3-Fe2O3 phase equilibrium diagram.
