Abstract

The DTA signal was studied in comparison with X-ray phase analysis of potassium nitrate particles in carbon nanotubes. It is shown that, for potassium nitrate particles in nanotubes, the temperature range of the existence of the KNO₃ ferroelectric phase expands up to 300 K and the ferroelectric and low-temperature paraelectric phases coexist.
