摘要：
The effects of La2O3-B2O3-TiO2 (LBT) glass addition on the phase composition, microstructure, and microwave dielectric properties of Ba0.2Sr0.8La4Ti4O15 (BSLT) ceramic were investigated in this study. X-ray diffraction results showed that a small amount of SrLaBO4 secondary phase was formed in the LBT-doped BSLT ceramics. Scanning electron microscopy indicated that addition of LBT glass restrained grain growth of the main phase. Samples doped with LBT showed strong promotion of both εr and Q × f values. Typically, the LBT (La2O3:B2O3:TiO2 = 1:0.5:0.5)-doped Ba0.2Sr0.8La4Ti4O15 ceramic sintered at 1550°C for 3 h in air exhibited good microwave dielectric properties of εr = 50.7, Q × f = 72,700 GHz, and τf = −7.3 ppm/°C.
