Abstract
Gd3+ modified LaPO4 (Gd
x
La1-x
PO4, where x = 0.02, 0.04 & 0.06) ceramics have been prepared using Auto Combustion. X-Ray diffractograms analysis shows that samples exhibits pure monoclinic structural phase upto x = 0.04 without presence of any other secondary phases whereas in x = 0.6, some secondary phases appears. The FESEM micrographs show grain growth, densification along with compactness of grains whereas EDS micrographs confirm the presence of elements according to stoichiometric proportion. Elemental mapping gives information about uniform distribution of elements. The dielectric relaxation behavior of prepared ceramics confirms from Cole-Cole model whereas dielectric loss gives information about conductivity of samples which has also be confirmed from conductivity profile.
