| 摘要 |
The invention intends to provide a precursor material for manufacturing dielectric fine particles, typically barium titanate particles, having uniform particle diameter and particle characteristics, and manufacturing method thereof. The composite oxide particles according to the present invention, which is the precursor material for barium titanate particles, substantially consists of 75 to 25 mol % barium titanate phase and 25 to 75 mol % titanium dioxide phase, and is produced by heat treating a mixed powder consisting of 100 mol % titanium dioxide particles and 25 to 75 mol % barium compound particles at 500° C. or more and less than 900° C.
