Dielectric constant of particles
"This thesis addresses to determine the dielectric constant of dielectric particles. The most significant use of dielectric materials is in capacitor applications. Military, automotive, telecommunications and data processing employ pervasive use of capacitive components. Many dielectric materials used in capacitor industry can be considered as two-phase systems. Polymer-ceramic capacitors are one of the obvious examples of this type of systems, but even pure ceramic capacitors often behave as two phase systems because of significant differences in grain and grain boundary properties. It is important to investigate dielectric properties of two-phase systems and attempt to extract parameters of each phase from this investigation. Concerning polymer-ceramic capacitors, dielectric properties of the particles as filler material are important to know. However, reliable and accurate measurement of dielectric constant of particles has not been reported. Different approaches have been used to estimate dielectric constant of ceramic particles. Dielectric constant of particles can be estimated by measuring the properties of powder compacts (green bodies). However particle properties can not be measured directly, but need to be calculated from the effective properties of the compacts by using mathematical models. Similar measurement can also be applied using ceramic slurries instead of powder compacts.
A new method is introduced for direct measurement of dielectric constant of particles by impedance spectroscopy. Dielectric constant of particles suspended in appropriate liquids were determined by analyzing of impedance spectra. The subject of this research was to analyze and calculate the dielectric constant of particles"--Abstract, page iv.
