Ferroelectric solid solution (SS) samples of the Li x Na1-x TayNb1-y O3 (LNTN) system were synthesized to have x = 0.12 and y = 0 - 1, the density exceeding 96% of the theoretical value determined by X-ray diffraction. The effects of isovalent substitution in the B sublattice of LNTN SS of the ABO3 structure on phase transition temperature has been examined in a wide temperature range (-190 - + 800°C). Concentrational structure transitions have been observed in the LNTN system at substitution of Nb by Ta in the B sublattice.
