چکیده انگلیسی
Microwave dielectric ceramics of tungsten–bronze-type BaSm2Ti4O12 were prepared by doping CuO (up to 2 wt.%) as the liquid-phase sintering aid. The effects of CuO additive on the densification, micro structure and dielectric properties were investigated. Due to the liquid-phase effect, the sintering temperature of BaSm2Ti4O12 ceramics with 1 wt.% CuO addition can be effectively reduced to 1160 °C, about 200 °C lower than that of pure BaSm2Ti4O12 ceramics, while good microwave dielectric properties of ɛr = 75.8, Q*f = 4914.6 GHz and τf = −7.65 ppm/°C were still achieved.
