Document Type and Number:
Japanese Patent JP7110305
Kind Code:
B2
Abstract:
To provide a method for producing barium titanyl oxalate that gives barium titanate with a small particle diameter and high crystallinity.SOLUTION: A method for producing barium titanyl oxalate, wherein barium titanyl oxalate is produced by mixing and reacting a solution containing oxalic acid (solution A) and a solution containing a titanium source and a barium source (solution B) with each other, the method being characterized by: separately supplying the solution A and the solution B to one end of a reaction liquid channel, mixing the solution A and the solution B with each other within the reaction liquid channel, discharging the reaction liquid out of the other end of the reaction liquid channel, and subsequently performing solid-liquid separation of the reaction liquid; and setting the residence time of the reaction liquid within the reaction liquid channel to 30 seconds or less.SELECTED DRAWING: Figure 1
