Abstract

Low-temperature sintered Ca[(Li_1/3Nb_2/3) _0.8Ti_0.2]O₃-δ microwave dielectric ceramics with ZnB₂O₄ glass (ZBG) addition were prepared by the conventional solid state reaction method. The sintering behavior, microstructure, and microwave dielectric properties of Ca[(Li_1/3Nb_2/3 )_0.8 Ti_0.2]O₃-δ ceramics with ZBG addition were investigated. The ZBG addition lowered the densified temperature of Ca[(Li_1/3Nb_2/3) _0.8Ti_0.2 ]O₃-δ ceramics from 1150°C to 940°C. The dielectric constants of Ca[(Li_1/3Nb_2/3) _0.8Ti_0.2]O₃-δ ceramics decreased from 40 to 34 and the temperature coefficient of resonant frequency (τ_f ) changed gradually from +12.7 to -25.7ppm/°C as ZBG addition increased from 0 to 8wt%. The Q_f values increased greatly from 20,500GHz of pure Ca[(Li_1/3Nb _2/3) _0.8Ti_0.2]O₃-δ to 26,900GHz when 5wt% ZBG was added. Ca[(Li_1/3Nb_2/3) _0.8Ti_0.2]O₃-δ ceramics with 8wt% ZBG addition sintered at 940°C show good microwave dielectric properties with ε_r ∼32.5, Q_f ∼20,600GHz, and τ_f ∼-25.7ppm/°C. The relationship between dielectric properties and microstructure was also discussed.
