Effects of Mg 2+ interstitial ion on the properties of Mg 0.5+x/2 Si 2-x Al x (PO 4 ) 3 ceramic electrolytes
Nasicon type, Mg0.5+x/2Si2-xAlx(PO4)3 was synthesized using citric acid assisted sol-gel method. The X-ray diffraction was applied to investigate the effect of extra Mg2+ interstitial ion on the phase, unit cell parameters and structure of the samples. The Mg0.625Si1.75Al0.25(PO4)3 sample exhibited...
