Abstract Scope |
This work is focused on the effect of conventional sintering (CS) and spark plasma sintering (SPS) process on the ionic conductivity of La and Zn co-doped Na3Zr2-xZnxLa0.66xSi2PO12 (NZZLSPx). Here, the difference in grain and grain boundary conductivity has been reported after conventional and spark plasma sintering. The relative density of sintered pellets increased in both sintering processes. However, the highest density in spark plasma sintered pellets was achieved as 3.33g/cc. SEM micrographs clearly show the presence of secondary phases such as faceted ZrSiO4. XRD patterns and its Rietveld refinements give the identification and quantification of different phases present, respectively. In both sintering processes, NZZLSP0.04 sample got the highest conductivity of 0.252 mS/cm in case of conventional sintering and 0.172 mS/cm in case of spark plasma sintering. It is also observed that there is a difference in highest grain conductivity obtained after doping between CS (0.589mS/cm) and SPS (6.19mS/cm) pellets. |
