摘要

A low-permittivity microwave dielectric ceramic BaZnAl₁₀O₁₇ (BZA) was synthesized via high-temperature solid-phase reaction. Its sintering behavior, crystal structure, and microwave dielectric properties were systematically studied. BZA can be sintered at 1575–1675 °C with uniform microstructure, ε_r = 8.75, Q × f = 34,783 GHz, and τ_f = -13.1 ppm/°C. Doping 0.5–2 wt% B₂O₃ reduced sintering temperature to 1500 – 1650 °C while maintaining good performance (ε_r = 8.39, Q × f =50,491 GHz, τ_f = −15 ppm/°C). BZA + 1 wt% B₂O₃ showed 97.8 % simulated radiation efficiency and 5.95 dBi gain at 11.5 GHz, with low loss and high thermal stability, promising for mobile communication base stations.
