Abstract
A new technique for measuring the conductivity of a single grain in a ceramic (polycrystalline) material is proposed. It is based on impedance spectroscopy where instead of conventional planar electrodes, microelectrodes acting as points electrodes are used. By measuring impedance at various positions on the surface of a polycrystalline material and analysing the set of results using a deconvolution procedure, it will be possible to separately determine the bulk grain and the grain-boundary conductivity. As model materials, AgCl and AgBr single- and polycrystals will be used.
