The dielectric properties of (Ag_xNa_(1-x))(Nb_yTa_(1-y))O_3 were investigated,and its dielectric loss and capacitance were measured.The dielectric properties of nanometer(Ag_xNa_(1-x))(Nb_yTa_(1-y))O_3 ceramic prepared by liquid method were better than that by conventional solid method.The average grain size of the nanometer powder(34 nm)obtained by citrate-gel method was small near 500 nm and homogeneous and the microstructure was dense and uniform.In addition,the sintering temperature had a great effect on properties.The dielectric properties of resultant samples were as follows:ε>500,tgδ<6 10~(-4),α_c<10 ppm/℃,ρ_v>1 012Ω·cm.
The dielectric properties of (Ag_xNa_ (1-x)) (Nb_yTa_ (1-y)) O_3 were investigated, and its dielectric loss and capacitance were measured. The dielectric properties of nanometer (Ag_xNa_ (1-x) -y)) O_3 ceramic prepared by liquid method were better than that by conventional solid method. The average grain size of the nanometer powder (34 nm) obtained by citrate-gel method was small near 500 nm and homogeneous and the microstructure was dense and uniformity. In addition, the sintering temperature had a great effect on properties. The dielectric properties of resultant samples were as follows: ε> 500, tgδ <6 10 -4, α_c <10 ppm / Cm
