Abstract
powder was captured using a confocal microscope. The electrical properties, including the dielectric constant, the loss factor, and the electrical modulus, have been determined in the temperature range of 313 to 433 K. Utilizing the Maxwell-Wagner effect as proposed by the Koop theory, the thermal variation of permittivity has been interpreted. The Kohlrausch-Williams-Watts equation (KWW) was used to assess the asymmetric curves of the electrical modulus.
