Solid state synthesis and characterization of iron (Ⅱ) pyrophosphate Fe2P2O7
摘要:
Offwhite pure Fe2P2O7 was synthesized through solid phase reaction using Fe2O3 and NH4H2PO4 in argon atmosphere. The reaction products of Fe2O3 and NH4H2PO4 at a series of temperatures from 400 to 900℃ were characterized by XRD. Comparison and analysis of XRD patterns of resultant products indicated well-crystallized Fe2P2O7 could be obtained over 630℃ and Fe2P2O7 prepared at 700℃ was triclinic in cell type. Comparison of the cell parameters proved that the as-prepared Fe2P2O7 belonged to β-Fe2P2O7 in crystal phase and SEM showed its size distribution was 0.5-2 μm.
