Deflocculants for Tape Casting Barium Titanate Dielectrics.
Abstract
The first part of this study has been directed towards understanding the mechanisms of dispersion for barium titanate after being exposed to Barium Titante powder, indicating that the ionic strength is sufficiently high for electrostatic repulsion. During this year the mechanisms by which the phosphate ester charges the barium titanate was clarified. Solvent conductivity is considerably enhanced after being exposed to the powder surface. This observation, in combination with the observation that the phosphate ester charges the surface positively, seems to indicate that the phosphate ester ionizes in the presence of the polar powder surface leaving the hydrogen ion on the surface. After losing the hydrogen(+) ion some of the anionic surfactant is absorbed on the surface and the rest is allowed to return into the solvent as an anion.
