Abstract
A method for producing a barium titanate-based powder, the method including: step a of spraying a raw material including a barium titanate-based compound into a high-temperature field heated to a temperature equal to or higher than a melting point of the compound to form barium titanate-based particles; and step b of heating a powder including the barium titanate-based particles formed in step a at 700 to 1300° C.
