Abstract
A group of dielectric compounds and mixtures of dielectric compounds with useful properties at microwave frequencies is disclosed. The dielectric materials are temperature compensated, have relatively high dielectric constants, and comprise the group of BaTi.sub.4 O.sub.9, and mixtures of Li.sub.2 TiO.sub.3 and Li.sub.4 Ti.sub.5 O.sub.12, MgTi.sub.2 O.sub.5 and TiO.sub.2, Zn.sub.2 TiO.sub.4 and TiO.sub.2, and BaTi.sub.4 O.sub.9 and TiO.sub.2.
