To provide a method for producing barium titanate powder which can control a particle diameter within 40 nm-300 nm in a solid phase method, has sharp particle size distribution, and high crystallinity and anisotropy, greatly reduce holes (defects) in particles to none or very few, and can control Ba/Ti as well, and to provide a method for producing an electronic component using the barium titanate powder.
The method for producing barium titanate powder using an aqueous titanium solution and barium salt powder as starting raw materials includes: a gelling step of mixing and gelling the starting raw materials; a drying step of drying the gelled mixture; a heat treatment step of heating the dried powder to generate barium titanate particles; and a separation step of separating the barium titanate particles from the heat-treated powder.
