Title:
蓚酸バリウムチタニルの製造方法及びチタン酸バリウムの製造方法
Document Type and Number:
Japanese Patent JP4638766
Kind Code:
B2
Abstract:
To provide barium titanyl oxalate in which the change of specific surface area to calcination temperature is suppressed to a low value in a stable quality and high yield.
The method for producing barium titanyl oxalate comprises adding an aqueous solution (a liquid A) containing titanium tetrachloride and barium chloride to an aqueous solution (a liquid B) containing at least an oxalic acid ion and an ammonium ion to carry out reaction. In the resultant barium titanyl oxalate, the molar ratio (Ba/Ti) of Ba to Ti is preferably <1, further preferably 0.990-0.999.
