ABSTRACT:
A production method of barium titanate according to the present invention comprises steps of preparing powder mixture of barium carbonate powder and titanium oxide powder and firing the powder mixture. The temperature of the powder mixture is raised to firing temperature at 100° C./minute or more in the range of 400° C. to 700° C.; and maximum temperature at firing is 700° C. or more. The present invention aims at providing a production method, wherein grain growth of barium carbonate particle can be controlled in temperature rising process when producing barium titanate by a solid phase reaction of barium carbonate and titanium oxide; and homogeneous barium titanate powder with small particle size can be produced with excellent energy efficiency.
