Estimating the term…
A system of dielectric ceramic compositions suitable for various microwave applications. The system comprises a plurality of stoichiometrically-related compositions, each composition having its own particular set of dielectric properties and consisting essentially of a sintered mixture represented by the general formula: BaTi.sub.4-w M.sub.w O.sub.9 --xZn.sub.2 TiO.sub.4 --yBaO--zTa.sub.2 O.sub.5 wherein M is at least one type of metal and 0.0.ltoreq.w.ltoreq.about 0.05 and wherein x, y, and z are molar fractions of respective components with values within the following respective ranges: 0.0.ltoreq.x.ltoreq.about 0.45; about 0.01.ltoreq.y.ltoreq.about 0.20; and 0.0.ltoreq.z.ltoreq.about 0.10.
A dielectric ceramic composition suitable for microwave applications consisting essentially of a mixture represented by the general formula:
A system of dielectric ceramic compositions comprising at least two different dielectric ceramic compositions, each dielectric ceramic composition possessing dielectric properties advantageously adapted for a different microwave application and consisting essentially of a mixture represented by the general formula:
