Samples of Mg0.5 Zr2 (PO4 )3 compound with pure NASICON-phase were obtained by coprecipitation method with magnesium nitrate,zirconium acetate and diammonium hydrogen phosphate as raw material.The Mg0.5 Zr2 (PO4 )3 (MZP)precursor powders were sintered via pressureless sintering and characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM)and electrochemical impedance spectroscopy (EIS). The results show that samples sintered at 750 ℃ by the pressureless sintering showed the highest total conduc-tivity of 4.67×10-6 S/cm and its density reached 90% of theoretical density.The activation energy of the sam-ples is 0.098 eV.The studies have shown that Mg0.5 Zr2 (PO4 )3 is a promising magnesium ion conductive materi-als and of great significance for the research of solid-state magnesium ion battery in the future.
