New binary systems of solid solutions based on NaNbO3

The complex investigations of new and known binary systems of solid solutions (SS), based on antiferroelectrics NaNbO3 (NN) with oxides, possessing columbite. KW-bronze, ilmenite and perovskite structure as second components: (1 - x)NN - xAIINb2O6 and (1 - x)NN - xAIITiO3 (AII - Ni. Cu, Mg, Co, Zn, Cd, Mn, Ca, Sr or Pb) have been conducted. The ferro- and piezoelectric properties with a wide range of values have been detected in all systems investigated. There are solid solutions, in which the detected values of electrophysical properties make them suitable for use in piezoelectronics.
