Dielectric properties of the ferroelectric composites [AgNa(NO2)2]0.9/[NaNO2]0.1 and [AgNa(NO2)2]0.9/[BaTiO3]0.1.

The effect of sodium nitrite and barium titanate particle inclusions on the dielectric properties and the Curie temperature of the ferroelectric AgNa(NO₂)₂ is studied. It is shown that the presence of 10 volume percent of BaTiO₃ particles increases the permittivity 4 times and raises the temperature of the phase transition by ΔТ_c ≈ 10 K. The presence of the NaNO₂ particles leads to the increase of dielectric permittivity of the composite, but it does not influence the Curie temperature. [ABSTRACT FROM AUTHOR]
