Abstract:
We report dense Na3Zr2Si2PO12 with an average grain size of 546 ± 58 nm and prepared by a facile method. The nano-grained Na3Zr2Si2PO12 exhibits an extremely high conductivity of 1.02 × 10-3 S cm-1 and low interfacial resistance of 35 Ω cm2 at 25 °C. Such processing facilitates the exploration of nanocrystalline conductors.
