Abstract

The purpose of the work. Research of the spectral depandence of the dielectric permittivity of polar dielectrics with different degree of packing of the crystal structure in the low frequency range.
Research methods. To obtain the spectral depandence of the dielectric permittivity of polar dielectrics used method of determining the capacitance of the capacitor, between the plates which are placed the sample under study. According to the received capacity value of the capacitor calculated value of the dielectric constant of the sample.
The results obtained. The authors obtained spectral depandence of the dielectric permittivity of dielectric materials with different degree of packing of the crystal lattice. Mathematical processing of the obtained experimental results allowed to establishing the linear character of the spectral depandence in logarithmic coordinates. Based on this proposed a power function adequately describing the spectral depandence of the dielectric permittivity of polar dielectrics at low frequencies.
Scientific novelty. The authors numerically determined power-law coefficient α, which depends on the nature of the dielectric and it can be regarded as a criterion of the packing density of the crystal lattice of the polar dielectrics.
Practical significance. The research results can be used to study the mechanism of polarization of polar dielectrics, used in electrical products under the influence of alternating electric fields of different frequencies.
