Abstract
Sintering characteristics and microwave dielectric properties of Mg4Ta2O9–5[Formula: see text]wt% B2O3 ceramics were investigated. With the sintering temperature increasing in the range of 1100[Formula: see text]C–1350[Formula: see text]C, the apparent density, [Formula: see text] and [Formula: see text] values increased firstly and then saturated at 1250[Formula: see text]C with excellent microwave properties: [Formula: see text], [Formula: see text][Formula: see text]GHz and [Formula: see text][Formula: see text]ppm/[Formula: see text]C. Compared to the pure MT ceramics, the B2O3 additives effectively decreased the sintering temperature of MT ceramics and had no detrimental effect on the properties of the MT ceramics due to the liquid phase effect.
