摘要：
We have prepared ceramic samples of solid solutions based on Bi-containing perovskite-like oxides near the morphotropic phase boundary in the K0.5Na0.5NbO3-BiScO3-AgSbO3 system and modified with LiF and MnO2 additions; investigated the phase relations, structure, and dielectric and ferroelectric properties of the ceramics; and determined their phase transition temperatures. The choice of superstoichiometric additives capable of intensifying the sintering process has been substantiated, and the effect of the additives on the Curie temperature of the ceramics has been examined.
