| Abstract: | Rare-earth doped strontium barium niobates were synthesized using usual ceramic technique. The dopants are La, Ce, Gd, Sm
and Nd. The materials were characterized by XRD and density measurements. The grain sizes were determined from SEM analysis.
Lattice parameters changed uniformly with rare-earth dopants in unfilled structures. Density measurements and SEM analysis
confirmed only minute changes in the densities of the ceramics. |
