Effects of Ca and Zr substitution upon the dielectric properties of Ba{sub 5}LaTi{sub 3}Ta{sub 7}O{sub 30} ceramics were investigated together with the structural characterization. All the samples of Ba{sub 5}La(Zr{sub x}Ti{sub 1-x}){sub 3}Ta{sub 7}O{sub 30} formed a filled tungsten-bronze structure...
