Title:
A manufacturing method of barium titanyl salt and barium titanate
Document Type and Number:
Japanese Patent JP5979645
Kind Code:
B2
Abstract:
The present invention addresses the problem of providing a method for producing a high-quality barium titanyl salt. This method includes: using, as the fluids to be treated, at least two kinds of fluids, namely, a barium titanium mixed solution that is obtained by dissolving both a barium compound and a titanium compound in a solvent, a compound solution that is obtained by dissolving, in a solvent, a compound capable of deposing the barium and titanium contained in the barium-titanium mixed solution into a barium titanyl salt, and if necessary, one or more other fluids; and mixing these fluids together in a thin film fluid formed at least between two treating surfaces (1) and (2) to form a barium titanyl salt. The treating surfaces (1) and (2) are so arranged as to face each other in an approachable/ separable state with one of the treating surfaces (1) and (2) being capable of turning relatively to the other. In the method, an acid substance is added to the barium-titanium mixed solution, the compound solution, and/ or a third solvent which is neither the barium-titanium mixed solution nor the compound solution, whereby a barium titanyl salt having a controlled barium/ titanium ratio can be obtained.
