Description
Summary:By means of a solid-phase synthesis two types of microwave dielectric materials are obtained as follows: Ba1-xSrx(Zn1/3Ta2/3)0.94Ti0.06O3, where x = 0.20, 0.25, 0.30, 0.35 and 0.40 at sintering temperature Ts = 1350, 1400 and 1450DGC; Ba(Zn1/3Nb2/3)1-xZrXO3, where x = 0.04, 0.06, 0.08 and 0.10 at Ts = 1300, 1350, and 1400 deg C. The microwave characteristics of the materials are investigated at f = 10 GHz. The composition Ba(Zn1/3Nb2/3)1-xZrXO3 demonstrates epsilonr = 38, Q = 6100 and tauf = +15 ppm DGC-1 and the composition Ba0.80Sr0.20-(Zn1/3Ta2/3)0.94Ti0.06O3 has epsilonr = 42, Q = 8200 and tauf = -13 ppmDGC-1. The composition Ba0.75Sr0.25(Zn1/3Ta2/3)0.94Ti0.06O3 has epsilonr = 40, Q = 6500 and low tauf = -13DGC-1 ppm. This composition could be used successfully for realisation of dielectric microwave resonators for the satellite television.
