Abstract :
Nasicon type compounds of general formula
Ca0.5SbMP3O12 (M = Al, Fe, Cr) are prepared by
solid-state method. All the compounds crystallize in
hexagonal lattice with R 3c space group. The IR spectra
show characteristic PO4 vibrations. Conductivity studies
indicate the presence of charged defects. The Cole-
Cole plots of impedance are semicircles between 150
and 350 C. The thermal expansion of these samples is
studied in the temperature range 25–500 C.
