Effects of Milling Time and Annealing Schedule on Mechanical Activation Synthesis of Brownmillerite Structural Ca2Fe2O5

Abstract:

Article Preview

The brownmillerite structural Ca2Fe2O5 is successfully prepared by high energy milling starting from CaCO3 and Fe2O3. The composition and transformation of phase and structure with different milling time and annealed at 800 °C for 24 h were characterized by the X-ray powder diffraction (XRD) and scanning electron microscopy (SEM) analysis. The results indicate that the high pure brownmillerite structural Ca2Fe2O5 could be efficiently synthesized at lower temperature by the mechanically activated mixtures.
