摘要
Ba3Ti4-x(Fe1/2Nb1/2)(x)Nb4O21 (0 <= x <= 4) ceramics with the substitution of (Fe1/2Nb1/2) for Ti were investigated. The modified Ba3Ti4-xNb4O21 dielectric ceramics prepared via the solid state reaction route exhibited single hexagonal structure. The dielectric constant and the quality factor of Ba3Ti4-x(Fe1/2Nb1/2)(x)Nb4O21 (0 <= x <= 4) ceramics decreased with an increase of x. Improved temperature coefficient of the resonant frequency of samples was obtained by the substitution of (Fe1/2Nb1/2) for Ti. Optimal microwave dielectric properties of epsilon(r) = 50, Q x f = 5200 GHz, and tau(f) = 10 ppm/degrees C in Ba3Ti2(Fe1/2Nb1/2)(2)Nb4O21 were obtained, which indicated its potential for microwave application.
