METHODS OF MAKING HIGH Q MODIFIED MATERIALS FOR HIGH FREQUENCY APPLICATIONS

Abstract:

Disclosed are embodiments of making a high Q ceramic material. The method includes providing Ba.sub.3CoTa.sub.2O.sub.9 and incorporating one of Ba.sub.2MgWO.sub.6, Ba.sub.8LiTa.sub.5WO.sub.24, Ba.sub.8LiTa.sub.5WO.sub.24, Ba.sub.2MgWO.sub.6, Ba.sub.3LaTa.sub.3O.sub.12, Ba.sub.8LiTa.sub.5WO.sub.24, BaLaLiWO.sub.6, Ba.sub.4Ta.sub.2WO.sub.12, Ba.sub.2La.sub.2MgW.sub.2O.sub.12, BaLaLiWO.sub.6, Sr.sub.3LaTa.sub.3O.sub.12, and SrLaTaO.sub.12 into the Ba.sub.3CoTa.sub.2O.sub.9 to form a solid solution having a high Q value of greater than 12000 at about 10 GHz.
