Mechanochemical synthesis of dicalcium ferrite with the perovskite structure from anhydrous or hydrated calcium and iron oxides was studied by XRD, DTA, IR spectroscopy, and Mossbauer measurements. The formation of Ca2Fe2O5 from anhydrous oxides during mechanical activation (MA) occurs at a high rate. Although hydrated oxides do not react during MA, Ca(OH)(2) dehydration and subsequent Ca2Fe2O5 formation in preactivated mixtures occur at much lower temperatures (the latter process, at 600 °С). The resulting product is well-crystallized and has a specific surface area of 13 m(2)/g, which is large enough for catalytic applications.
