Abstract

The effect of BiTaO₄ addition on the sintering behavior and microwave properties in BiNbO₄ ceramics was studied. Ta was used to substitute Nb to adjust small temperature coefficient of resonate frequency (τ_f) and improve high quality factor (Q * f) values. The dielectric constant saturates at 44-45 in spite of the amount of Ta. The Q * f reaches a maximum value of 21,000 GHz for BiNb_0.4Ta_0.6O₄ ceramic sintered at 940 °C for 3 h. The τ_f can be adjusted from 15 ppm °C^-1 to 40 ppm °C^-1 by varying the Ta content from 0 to 1. A zero τ_f value can be obtained by properly adjusting the Ta content.
