Phase analyses of Na ion-conducting glass-ceramic composites
NaSICON-type compounds with the general composition Na1+xZr2SixP3-xO12 are again more intensively investigated for battery applications. In an attempt to better understand the phase formation of NaSICON compositions with Zr deficiency, we are exploring two series of compositions, both with an increasing Zr deficiency, but with stoichiometric and excess of (P + Si) content. The proposed experiments shall primarily elucidate the final compositional variation in the crystalline phase along the two series. Additional information on the formed glassy phase would be very helpful to understand the whole system. The quantification of the glassy phase and its constituents is important to understand the chemical equilibria at high temperatures. The X-ray atomic scattering factors of light atoms (here Na and O) are very low and Si and P have only one electron difference, which makes an accurate determination of the final crystalline NaSICON compositions impossible by XRD technique.
