Abstract

(Sr_0.9Ba_0.1)La₄Ti₄O₁₅+xwt%Nd₂O₃(0≤x≤8, BSN) ceramics were prepared by the conventional solid state processing method, the microstructure and microwave dielectric properties of BSN ceramics were investigated. The results show that adding Nd₂O₃ into BSN ceramics would lower the sintering temperature, a few of La₂TiO₅ phase was also observed in the ceramics besides SrLa₄Ti₄O₁₅. With increasing the content of Nd₂O₃, the dielectric constant and the temperature coefficient of resonance frequency changed little, but the value of Q×f increases obviously. (Sr_0.9Ba_0.1)La₄Ti₄O₁₅+4%Nd₂O₃ ceramic shows the optimal dielectric properties of ε_r=43.2, Q×f=42015 GHz (6.024 GHz), τ_f=-9.6 μ℃^-1.
