Measurement of dielectric constant of BaTiO₃ powders by impedance spectroscopy
Keywords and Phrases
"The objective of this thesis is to contribute to the reliable measurement of the dielectric constant of particulate materials by applying impedance spectroscopy techniques to slurries. Slurries were prepared by dispersing dielectric powders, such as BaTiO₃, in appropriate host liquids. The impedance spectrum of the slurry consists of two frequency dependent semicircles: Maxwell relaxation in the host liquid is responsible for the high frequency semicircle, whereas low frequency relaxation is due to the dispersed powder. This finding was confirmed by measuring slurries prepared using different powders and host liquids, as well as by variation of slurry solids loadings. Experimental modeling studies were also conducted"--Abstract, leaf iv.
