Abstract
We have developed a technique for the preparation of a dielectric ceramic CaCu3Ti4O12 filler and submicron dispersions of the filler in epoxy. The crystal structure of CaCu3Ti4O12 has been refined using high-resolution neutron diffraction data with anisotropic atomic displacement parameters. We have studied the particle size distribution and rheological properties of CaCu3Ti4O12 dispersions and, using rheological data, identified the surfactants that ensure Newtonian rheology of dispersions, convenient for filling porous templates. Surfactants have been shown to have a significant effect on dielectric characteristics of filled epoxy compositions.
