Single-phase (Na_0.5Bi_0.5)(Ti_{1 – x}Co_x)O₃ (x = 0–0.1, ∆х = 0.02) ceramic samples have been prepared by solid-state reactions, and their structure, microstructure, and dielectric properties have been studied. In all of the synthesized samples, a perovskite phase with a pseudocubic unit cell has been identified. Partial substitutions of cobalt cations for titanium cations increase the unit cell volume of the samples. We have studied the dielectric properties of the ceramics. The increased room temperature dielectric permittivity of the samples can be interpreted as evidence that the acceptor doping performed in this study has an advantageous effect on the piezoelectric properties of the sodium bismuth titanate ceramics.

单相（Na _0.5 Bi _0.5）（Ti _{1 – x} Co _x）O ₃（x = 0–0.1，∆х= 0.02）已通过固相反应制备了陶瓷样品，并对它们的结构，微结构和介电性能进行了研究。在所有合成样品中，均已鉴定出具有伪立方晶胞的钙钛矿相。钴阳离子被钛阳离子部分取代会增加样品的晶胞体积。我们已经研究了陶瓷的介电性能。样品的室温介电常数的增加可以解释为证​​据，表明在这项研究中进行的受体掺杂对钛酸铋钠陶瓷的压电性能具有有利的影响。
