Good quality crystals of K$_{3}$Li$_{2}$Nb$_{5}$O$_{15}$ type were grown from the melt followed by method slow cooling using a pseudo-flux method (an excess of K$_{2}$CO$_{3}$ and Nb$_{2}$O$_{5}$ is present). The crystals were identified by X-ray diffraction, they crystallized with the tungsten bronze-type structure in the tetragonal system at room temperature. The space group is P4bm. Their composition (K$_{2.82}$(Nb–O)$_{0.08}$Li$_{1.54}$Nb$_{5}$O$_{15}$) was determined by chemical analysis. Dielectric measurements were realized along the [001] and [100] directions in the frequency range from 10$^{3}$ to $3 \times 10^{5}$ Hz. The temperature dependences of dielectric constants $\varepsilon^{\prime}_{\rm r33}$ and $\varepsilon^{\prime}_{\r...
