摘要：

Mechanochemical synthesis of the K0.5Na0.5NbO3 solid solution (KNN) is studied. In order to explore the mechanochemical interactions between the constituents in the Na2CO3 - K2CO3 - Nb2O5 system, NaNbO3 and KNbO3 as the boundary compositions of the KNN solid solution are also studied. It has been shown that NaNbO3 can be prepared by a single-step mechanochemical synthesis, while in the case of K2CO3 and Nb2O5, and Na2CO3, K2CO3 and Nb2O5 mixtures, only amorphisation occurs even after prolonged milling.
