摘要：
A new polycrystalline material Na3Co7(PO4)(6) has been synthesized by solid-state (ST) and sol-gel (SG) methods and characterized using powder X-ray diffraction (XRD) to solve the structure, which is found to crystallize in the monoclinic system with a P21/c space group. Scanning electron micrographs showed the particles as aggregates with grain sizes ranging from 8 to 35 mu m and 1 to 20 mu m, for Na3Co7(PO4)(6)-ST and Na3Co7(PO4)(6)-SG, respectively. Energy-dispersive X-ray Spectroscopy (EDS) confirms the presence of Na, Co, P, O elements and their homogenous distribution in the samples. The X-ray photoelectron spectroscopy (XPS) results indicate that the oxidation states for these elements are Na(I), Co(II/III), P(V) and O(-II). The optical bandgaps of Na3Co7(PO4)(6)-ST and Na3Co7(PO4)(6)-SG were estimated to be 1.79 eV and 1.78 eV, respectively, based on the UV-Vis diffuse reflectance spectra. The ionic conductivity for both samples is found to be 3.7 x 10(-4) S/cm at 300 degrees C and 6.53 x 10(-2) S/cm at 450 degrees C.
