In this study, a sol-gel process was modified and used to synthesise gel precursors of MgCe4P6O24 ceramic electrolyte. TGA-DSC profiles predicted the calcination temperature of MgCe4P6O24 dried gel precursors at 900 o C. XRD patterns show that a single phase MgCe4P6O24 ceramic electrolyte was formed after the gels were calcined at 900 o C, and there was no phase transformation after the pelletised calcined nanopowders were sintered at 1300 0 C. XRD analysis revealed that the dried gel precursor powders calcined at 900 o C shows a monoclinic crystalline phase structure with an average crystallite size of 52±1 nm, which is consistent with results from the high-resolution TEM (HRTEM). Whereas the TGA-DSC profiles show a single phase MgCe4P6O24 ceramic electrolyte at 900 o C, thermodynamic stability of the sintered MgCe4P6O24 ceramic electrolyte is held at 1300 o C. Electrical properties of platinised MgCe4P6O24 ceramic electrolytes analysed using electrochemical impedance spectroscopy (EIS) exhibits an improved bulk ionic conductivity of 10 -3 Scm -1 at 744 o C, which is considered suitable as an ionic conductor in fabricating solid-state Mg-sensors.

“…al (1976) [3] in the system of Na 1+x Zr 2 Si x P 3-x O 12 [2] . Since then, various studies have focused on lithium analogous NASICON structured with the general formula LiM 2 P 3 O 12 with M = Ti [4,5], Zr [6,7],Sn [8][9][10] and etc. Lithium analogous NASICON structured electrolytes are made of a three−dimensional framework of TiO 6 octahedra and PO 4 tetrahedra with interstitial tunnels in which Li-ions can hop easily [11][12][13].…”

Electrical properties of Li - ion conducting Li1+xCrxSn2-x(PO4)3 ceramic electrolytes with 0 < x < 1 were studied using electrical impedance spectroscopy in the frequency range of 1 Hz to 10 MHz at room temperature. Impedance analysis showed an increase in bulk and grain boundary conductivity with the increment of x up to x = 0.7. The highest bulk and grain boundary conductivity were 6.52 ×10-6 S cm-1 and 1.62 ×10-6 S cm-1 in the system of Li1.7Cr0.7Sn1.3(PO4)3 at room temperature. The charge carrier concentration, mobile ion concentration, ionic hopping rate and ionic mobility were calculated by fitting the AC conductivity spectra. The ionic hopping rate and ionic mobility of the compound increased with the substitution of chromium due to the extra interstitial Li+ ions in the system. Additionally, the highest conducting sample with x = 0.7 had a negligible electronic conductivity based on transference number measurements. These results imply that the Li1+xCrxSn2-x(PO4)3 electrolytes obtained in this work can be considered as future candidates for solid state electrolytes.
