A novel low-fired microwave dielectric ceramic, BaCu(B2O5)-added 0.6Ca(3/5)La(4/15)TiO(3)-0.4Li(1/2)Nd(1/2)TiO(3) (abbreviated CLT-LNT), was prepared by solid state route. The influence of BaCu(B2O5) on the phase composition, sintering behavior and microwave dielectric properties of as-synthesized CLT-LNT ceramics was investigated. All the BaCu(B2O5)-added CLT-LNT ceramic samples exhibited single phase orthorhombic perovskite structure. BaCu(B2O5) dramatically decreased the sintering temperature of CLT-LNT ceramics from 1400 to 930 A degrees C. Favorable microwave dielectric properties (epsilon(r) = 87.6, Q x f = 6530 GHz, tau (f) = 3.2 ppm/A degrees C) as well as the maximum relative density (97.9%) were obtained for the 1.6 wt% BaCu(B2O5)-added CLT-LNT ceramic sintered at 930 A degrees C for 3 h. Therefore, such a novel BaCu(B2O5)-added CLT-LNT ceramic would be a promising candidate for low-temperature co-fired ceramics applications.
