New binary systems of solid solutions based on NaNbO3

The complex investigations of new and known binary systems of solid solutio ns (SS), based on antiferroelectrics NaNbO3 (NN) with oxides, possessing co lumbite, KW-bronze, ilmenite and perovskite structure as second components: (1 - x)NN - xA(II)Nb(2)O(6) and (1 - x)NN - xA(II)TiO(3) (A(II) - Ni, Cu, Mg, Co, Zn, Cd, Mn, Ca, Sr or Pb) have been conducted. The ferro- and piezo electric properties with a wide range of values have been detected in all s ystems investigated. There are solid solutions, in which the detected value s of electrophysical properties make them suitable for use in piezoelectron ics.
