Abstract
Rare earth ion (Nd, Sm, La and Ce) doped CaTiO3-SmAlO3 ceramics were obtained
from corresponding oxides by thermal decomposition method and sintering at
different temperatures up to 1370?C. The microstructure, densification and
dielectric properties were systematically studied. The relationship between
microstructure and dielectric properties was also correlated to understand
the key contributor which improves quality factor. Relative dielectric
constant of ?r ? 39.3 and the highest quality factor Q ? f = 49430GHz with
small temperature coefficient ?f of ?9.4 ppm/K were obtained for the
CaTiO3-Sm0.85Nd0.15AlO3 sample doped with 1.5 at.% Ce.
