Synthesis of Monoclinic Form of Gd_2-xNa_xCuO₄ by Direct Precipitation from Molten Salt

Institute of Chemistry Chinese Academy of Sciences Beijing 100080

Received Date: 20 September 1999

A new phase of Gd_2-xNa_xCuO₄ was synthesized by direct precipitation from the mixture of Gd2O₃ and CuO in the molten KOH/NaOH/KNO₃ solution at temperature as low as 280℃.The resulting precipitate was characterized by using SEM, XRD, EDX, XPS and magnetic method.The XRD data indicate that the precipitated Gd_2-xNa_xCuO₄ is monoclinic with lattice parameters a=8.6816Å, b=3.7233Å.c=6.0796Å, α=γ=90°, β=108.75° and v=186.1Å3.
