概要

BaTiO_3 ceramics were made by changing firing temperature and amount of addition of clay. The grain size of samples were classified according to ASTM designation. the ceramics with same dielectric constant (1500) and grain size ranging from 1.2μ to 14μ were picked up as the samples. Some electrical properties were measured as a function of grain size. The results obtained were summarized as follows: (1) Dielectric loss was increased with the increasing of grain size. (2) Harmonic distortion due to polarization with long relaxation time was increased with the increasing of grain size. (3) Remaining electric charge was sharply increased at the grain size of 10μ and above
