摘要: Phosphosilicate molecular precursor for the synthesis of NASICON, natrium super ionic conductor, Na1+xZr2SixP3−xO12 (x = 1 and 2) has been devised prepared by hydrolysis tetraethoxysilane (TEOS) employing sodium phosphate solution. The was reacted with Zr(OC3H7)4 in ethanol under solvolytic condition to yield nano material NASICON. This annealed at high temperature phase-pure characterized using 31P NMR, FTIR spectral data, powder XRD pattern TG/DTA studies. structure deduced from which indicates presence edge sharing tetrahedral arrangement −O−Si−O−P−O−Si− chain. NASICON TG/DTA, FTIR, TEM, SEM, MAS NMR XRD. conductivity synthesized measured pellet 900 °C found be 5.5 x10−3 S cm−1. details on preliminary inves...
