The results of a study of composites (KNO3) 1 -x /(BaTiO3)x (x = 0.1 and 0.2) are presented. It is shown that the stability of the ferroelectric state of potassium nitrate increases with an increase in the volume fraction of inclusions. It was found that the stability of the ferroelectric phase of potassium nitrate in the composite is also influenced by the particle size of the inclusions. It was revealed that the values of the dielectric constant in the region of the ferroelectric phase increase with an increase in the particle size of the inclusions.
