Abstract
Modification of the dielectric properties of Ba4Sm2Ti4Ta6O30 ceramics by Sr
substitution for Ba on the A-sites and Ti substitution for Ta on the B-sit
es was investigated. With increasing Ti concentration, the temperature coef
ficient of the dielectric constant was significantly improved together with
decreased dielectric loss and slightly decreased dielectric constant. The
minimum temperature coefficient of -470ppm/degreesC was obtained in the com
position of Ba2Sr2Sm2Ti4+xTa6-xO30-x/2(x = 3.0) with epsilon = 111, Qf = 20
