Abstract:
Several studies have been made of the calcium ferrite system by synthesis of pure oxides with lime which revealed that ferrite forms in two systems i.e. CaO-Fe2O3 and CaO-FeO-Fe2O3. Industrial sintering is more complicated at it involves additional components such as MgO, A1203 and SiO2. Although Ferrites in these sinters have been 'reported to form in CaO-Fe2O3-Al2O2 and CaO-Fe2O3 = A1203 –SiO2 systems, but little information is available regarding their chemical range and no work has been done to reveal their crystal structures and the mechanism through which they form. This deals with the electron diffraction work on industrial as well as synthesized sinter specimens. The chemical composition range of the calcium ferrite, the crystal structure and the mechanism of their formation is discussed.
