Frequency-dependent electrical behaviour of Na2SiO3: a brief report
Source abstract
Abstract
The present study reports the frequency-dependent electrical properties of sodium silicate (Na2SiO3) (SS) at different temperatures to understand the contribution of grain and grain boundary polarization to its electrical response at a lower frequency region. The low-frequency dielectric dispersion and non-Debye-type dielectric relaxation are attributed to polaron hopping that controls the complex impedance of SS. A single semi-circular arc in Nyquist plot indicates a dominance of grain boundary polarization in the relaxation mechanism. The analysis of frequency-dependent ac conductivity in the studied temperature regime can be used to define the correlated barrier hopping model.
