摘要

PURPOSE:To manufacture barium titanate or strontium titanate powder having a small and uniform particle size by reacting titanium oxide hydrate with barium hydroxide or strontium hydroxide under heating in the presence of a large amount of water. CONSTITUTION:Titanium oxide hydrate, preferably orthotitanic acid is reacted with barium hydroxide or strontium hydroxide at 60-110 deg.C in the presence of water added by an amount (mole) 120-10,000 times the amount of the titanium oxide hydrate (expressed in terms of titanium). At this time, stirring is preferably carried out while preventing CO2 from entering the reaction system. Spherical powder of barium titanate or strontium titanate having a small and uniform particle size and a small specific surface area is synthesized. The powder is hardly coagulated.
