Abstract
The study of crystal structure temperature evolution of the ferroelectric composites (1 − х)NaNO2 + (x)KNO2 at х = 5, 10 и 20 vol. % has been performed by neutron diffraction. The temperature dependencies of the ferroelectric order parameter η(т) for sodium nitrite have been determined in the composites and pure NaNO2. They coincide on heating and cooling and do not depend on KNO2 concentration. The increasing of KNO2 structural phase transition temperature (∼10–15 K) has been revealed in the composites in comparison with pure KNO2.
