Abstract

BaO-CeO₂-TiO₂ microwave dielectric ceramics with the different content of TiO₂ were fabricated by a solid-state reaction method using BaCO₃, CeO₂, TiO₂ powders as starting materials in view of the dispute. The sintering characteristics, phase composition, micro-structures and microwave dielectric properties of BaO-CeO₂-nTiO₂ microwave dielectric ceramics with different n values sintered at different temperatures were investigated. The results showed that the sintering temperature of BaO-CeO₂-nTiO ₂ microwave dielectric ceramics was lower (< 1300°C), and CeO₂ didn't tend to form polynary compounds. When n = 3, the sintered ceramics had excellent dielectric properties: ε_r ≈40.3, tanδ ≈1.02×10^-3 (1 MHz); ε_r ≈ 41.2, Q·f =19922GHz (6.865 GHz), τ_f = +22 ppm/°C.
