Mg_{1 -x}Cu_x TiO₃ (0.00 ≤ x ≤ 0.20) microwave ceramics were prepared by the solid - state reaction method. The effects of CuO sintering aids on the microstructure and microwave dielectric properties of MgTiO₃ ceramics were investigated. It was shown that the Cu²⁺ ions could enter the MgTiO₃ lattice and substitute Mg²⁺ ions forming Mg_{1 -x}Cu_xTiO₃ solid solution. A moderate amount of CuO can promote the densification sintering of MgTiO₃ ceramics and reduce the sintering temperature due to the liquid phase. The A-site substitution of Cu²⁺ ions alters the distortion of the TiO₆ octahedra. With the increase of Cu²⁺ ions content in MgTiO₃ ceramics, the structural stability was weakened. With the addition of CuO content, the quality factor (Qf) of the sample decreased owing to inhomogeneous grain growth and the appearance of the liquid phase. Meanwhile, the reduction of relative density, structural stability, and average covalency of Mg_1-xCu _xTiO₃ ceramics would deteriorate the Qf value of the sample. The dielectric constants (ε_r) of samples were related to the ionic polarizability, impurity phase, and TiO₆ octahedra distortion. The temperature coefficients of resonant frequency (τ_f) decreased with the increase of TiO₆ octahedra distortion. When x= 0.08, the sample could achieve densification sintering at 1 150 ℃ and the τ_f value was improved to -3.4×10^-5 ℃^-1.
