The dielectrics of Ba{sub 6}Ti{sub 2}Ta{sub 8}O{sub 30} and Sr{sub 6}Ti{sub 2}Ta{sub 8}O{sub 30} were prepared and characterized. These compounds have the tetragonal tungsten-bronze structure and paraelectric nature at room temperature. Very low dielectric loss was determined at 1 MHz in both dielectrics together with a relatively small temperature coefficient. The dielectric constant was 174 and 180 for Ba{sub 6}Ti{sub 2}Ta{sub 8}O{sub 30} and Sr{sub 6}Ti{sub 2}Ta{sub 8}O{sub 30}, respectively.
