      abstract     = {Al/Y-substituted NASICON solid electrolytes are promising
                      for novel solid state batteries. The solid solutions
                      Na1+2xAlxYxZr2-2x(PO4)3 (NAYZPx) and
                      Na3+2xAlxYxZr2-2x(SiO4)2(PO4) (NAYZSiPx) that crystallize in
                      this structure are characterized by depth-sensitive
                      indentation technique to determine their micro-mechanical
                      properties. NAYZPx is rhombohedral, whereas NAYZSiPx changes
                      from monoclinic to rhombohedral phase depending on
                      substitutional level and temperature. For rhombohedral
                      NAYZPx elastic moduli are in the range ~72–82 GPa and
                      hardness values are in the range ~4.8–5.8 GPa, whereas
                      for NAYZSiPx the elastic moduli are with the range
                      ~72–88 GPa and hardness ~5.6–7.6 GPa, respectively.
                      The fracture toughness values for both systems, as
                      determined by Vickers indentation, are rather independent of
                      the applied load being with the range
                      1.30–1.58 MPa m0.5. Cracks typically show a mixed
                      intergranular/transgranular crack mode.},
