abstract = {Scandium-substituted NASICON (Na3.4Sc0.4Zr1.6Si2PO12) is a
promising electrolyte material for sodium-ion solid state
batteries, with the highest ionic conductivity reported to
date for a NASICON material. Low-temperature densification
and control of microstructure are important factors to
enable the low-cost manufacturing of such new battery type.
Non-conventional sintering techniques such as Field Assisted
Sintering Technology / Spark Plasma Sintering (FAST/SPS) and
Cold Sintering are therefore investigated and compared to
conventional free sintering. FAST/SPS enables to get rapidly
dense samples $(99\%$ TD) at lower temperatures than the
ones required by conventional sintering routes and with
similar electrical properties. Cold sintering experiments,
involving the addition of aqueous solutions as sintering
aids and high mechanical pressure, enable a moderate
densification, but at temperatures as low as 250 °C.
Further heat treatments still below the conventional
sintering temperature increased the achieved density and
ionic conductivity.},
