BARIUM TITANATE DISPERSION COMPOSITION

摘要

Disclosed is a barium titanate dispersion composition exhibiting good dispersibility of a barium titanate powder in a polar solvent. This barium titanate dispersion composition leaves no residuals when the barium titanate dispersion composition using a polar solvent is coated and sintered. Specifically disclosed is a barium titanate dispersion composition which is obtained by dispersing a barium titanate powder in a dispersion medium while using a terminally carboxylated polylactone compound as a dispersing agent. The terminally carboxylated polylactone compound is obtained by ring-opening polymerizing a lactone compound while using, as an initiator, at least one substance selected from hydroxycarboxylic acids and condensation products of hydroxycarboxylic acids. The weight average molecular weight of the terminally carboxylated polylactone compound is 500-5000.
