  • Characterization of Dielectric Particles by Impedance Spectroscopy (Part I)
    Journal of the American Ceramic Society, 2008
    Co-Authors: Vladimir Petrovsky, Tatiana Petrovsky, Swetha Kamlapurkar, Fatih Dogan
    Abstract:

    Impedance Spectroscopy is an effective method to investigate physical properties of multicomponent systems so that contributions of individual components can be extracted from different sections of the spectra, which is frequency dependent. Slurries can be considered as 0-3 mixed systems containing a host liquid and dispersed particles. It was shown that low-frequency part of Impedance spectra is sensitive to dielectric properties of dispersed particles. Applicability of this technique was extended using various dielectric powders dispersed in appropriate liquids. Characterization of slurries by Impedance Spectroscopy through applying of equivalent circuit models allows a reliable measurement of dielectric constant of particulate materials and liquids.

  • Dielectric constant of particles determined by Impedance Spectroscopy
    Journal of Applied Physics, 2006
    Co-Authors: Vladimir Petrovsky, Abhishek Manohar, Fatih Dogan
    Abstract:

    Electrical characterization of slurries prepared by mixing dielectric powders with solvents can be used to estimate dielectric properties of the particles. In particular, dielectric constant of the particles can be calculated from effective dielectric constant of the slurry measured at high frequency by using the Lorentz-Lorenz or similar equations based on mixing rules. Unfortunately, this approach leads to high margin of errors in dielectric constant estimation and is very sensitive to any slurry nonidealities such as sedimentation or agglomeration of particles. Impedance Spectroscopy techniques are introduced to measure dielectric properties of particles at different frequency ranges. Dielectric constant of strontium titanate particles, suspended in butoxyethanol, was determined reproducibly by Impedance Spectroscopy using an appropriate equivalent circuit model.
