Mechanochemical synthesis of NaNbO3, KNbO3 and K0.5Na0.5NbO3

Mechanochemical synthesis of NaNbO3, KNbO3 and K0.5Na0.5NbO3

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 sh...
