Abstract
The effect of barium titanate particles (2–30 μm) on the ferroelectric properties of potassium nitrate in a (KNO3)1 − x -(BaTiO3) x composite is studied for x ranging from 0 to 0.5. It is shown that the dipole-dipole interaction between individual components in the ferroelectric composites can lead to changes in the properties of the initial ferroelectric materials. The degree of impact of BaTiO3 particles on the temperature range of existence of the ferroelectric phase in KNO3 is determined not only by the concentration of these particles but also by their sizes.
