Description

Na-ion conducting Na3+x[ZrxSc2-x(PO4)3] (x = 0, 0.25, 0.5 and 0.75 mol%) glass samples with NASICON-type phase were synthesized by melt quenching method and glass-ceramics were formed by heat treating the precursor glasses at their crystallization temperatures. The major and minor crystalline phases such as [Na3Sc2(PO4)3 (ICSD-27740) (NASICON), ZrP2O7 (ICSD-15084), ZrO2 (ICSD-66781) and Zr2O(PO4)2 (ICSD-1922)] are precipitated in all the glass-ceramic samples. The best bulk conductivity has been observed for Na3.5Zr0.5Sc1.5(PO4)3 glass-ceramic sample (σb = 1.92 x 10-4 S/cm) which exhibits lowest activation energy of 0.492 eV. The single master curve in the scaling analysis revealed that this glass samples show evidence of temperature-independent conduction transport mechanism. (orig.)
