Preparation and sintering of Ba2Ti9O20-based ceramics and their properties for dielectric resonators

The present paper was intended to study the grain-size influence of the oxide reagents used and the chemical treatment method applied of dibarium nonatitanate-based dielectric ceramics used as dielectric resonators in high-frequency fields. On the obtained samples, the main ceramic and electric properties were determined. The dielectric characterization of the resonators obtained, as well as the effects determined by their utilization within a stable frequency oscillator, was achieved by measurements in a high-frequency field.
