Abstract
The microwave properties of numerous perovskite antimonates like A,MeSbO,where A=Ba or Sr, Me=a rare earth, Y, Sc, Ga, or In and A,MeSb,O,where A=Ba or Sr and M=Li, Na or K were measured at 10 Ghz and 300 K. Using the microwave properties and lattice parameters of these materials, the Clausius-Mossotti relationship and a nonlinear regression fitting program, the polarizability of Sb,was investigated and determined to be 1.18±0.49 A,. This low polarizability and the low loss of antimonates in general indicate that Sb,is an excellent candidate for use as a constituent in the fabrication of low dielectric constant, low loss, lattice matching perovskite oxide microwave substrates.
