| 摘 要： | Offwhite pure Fe_2P_2O_7 was synthesized through solid phase reaction using Fe_2O_3 and NH_4H_2PO_4 in argon atmosphere.The reaction products of Fe_2O_3 and NH4_H_2PO_4 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 Fe_2P_2O_7 could be obtained over 630℃and Fe_2P_2O_7 prepared at 700℃was triclinic in cell type.Comparison of the cell parameters proved that the as-prepared Fe_2P_2O_7 belonged toβ- Fe_2P_2O_7 in crystal phase and SEM showed its size distribution was 0.5-2μm.

| Abstract: | 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 °C were characterized by XRD. Comparison and analysis of XRD patterns of resultant products indicated well-crystallized Fe2P2O7 could be obtained over 630 °C and Fe2P2O7 prepared at 700 °C 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. |
