It was established that the dielectric ceramics (BaTi4O9 + 8.5% ZnO, TCC = 0 Qf at 10 GHz), fulfilled all the requirements for materials for resonators and can be used by the co-executors of this project (Institute of General and Inorganic Chemistry named after V.I. Vernadsky), for the manufacture of dielectric resonators and resonator inserts. The Raman studies of synthesized ceramics have made it possible to confirm that the synthesized ceramics correspond exactly to the phase planned during the synthesis. It has been demonstrated that this method is effective in controlling the formation of a certain phase of dielectric ceramics and allows it to determine the presence of impurities in other phases.
