Abstract
BaTiO3-Nb2O5-xBi4Ti3O12 ceramics are prepared by a conventional mixed oxide route. From the observations, the proverskite-type solid solutions are formed for x ≤ 0.075, and second phase BaBi4Ti4O15 is found for x > 0.2. The sintering temperature is reduced effectively to 1090°C. A progressive decline in ϵr max with increasing x led to near temperature-stable dielectric properties over a wide temperature range. For x = 0.15, ϵr max = 772(Δϵ/ϵ25 °C≤ 15%), from −55°C to 400°C, and tan δ≤ 0.02 from −55°C to 192°C. This work provides a roadmap to obtain a temperature-stable dielectric ceramic.
