Description
Summary:The solid solutions of the (1-x)Na[Formula: see text]Bi[Formula: see text]TiO3-xNa[Formula: see text]K[Formula: see text]NbO3 system were produced by the conventional ceramic technology using mechanical activation of the synthesized product. It was found that in the (1-x)Na[Formula: see text]Bi[Formula: see text]TiO3-xNa[Formula: see text]K[Formula: see text]NbO3 system at room temperature, a number of morphotropic phase transitions occur: rhombohedral → cubic → tetragonal → monoclinic phases. The introduction of a small amount of Na[Formula: see text]K[Formula: see text]NbO3 leads to an increase in the temperature stability of the dielectric properties of ceramics. A change in the relaxor properties of the solid solutions of the (1-x)Na[Formula: see text]Bi[Formula: see text]TiO3-xNa[Formula: see text]K[Formula: see text]NbO3 system was shown. The increase in energy density and energy efficiency was found at additive 10[Formula: see text]mol.% of Na[Formula: see text]K[Formula: see text]NbO3.
