Summary

Impedance spectroscopy (IS) is a nondestructive electrical characterization technique that is used in a wide range of research and process-control applications. In this project, IS is assessed as a tool to study the microstructural and chemical behavior of clay-based systems. Features in impedance spectra can be attributed to the bulk body (pore fluid and solids) and the bulklelectrode interface. An equivalent circuit of the bulk response is modeled from the spectra and correlated to moisture content, porosity, and ionic strength of the pore fluid. The potential of impedance spectroscopy as a process-control technique in whitewares manufacturing will be discussed.
