Electrical properties of sol–gel processed NASICON having new compositions

Abstract High-conductivity and high-density samples with new compositions in the NASICON-type electrolyte series, i.e., the Na 3 Zr 2−( x /4) Si 2− x P 1+ x O 12 system, with x =0(A), 0.667(B), and 1.333(C) were synthesized using a mixed inorganic–organic sol–gel process. The sinterability was improved with increasing the x value, but the conductivity decreased. Highly dense samples were obtained by sintering at 1100°C. The conductivity decreased with decreasing the c lattice parameter of the hexagonal structure. Nevertheless, the CO 2 gas sensors using the highly dense B and C samples showed good EMF response which is very close to the theoretical value.
