DIELECTRIC COMPOUND AND MANUFACTURING METHOD THEREOF

WIPO Patent Application WO/2010/064686

A1

Provided are a dielectric compound and a method for manufacturing said compound with which dielectric compounds such as RFe2O4 can be efficiently synthesized. In the manufacture of a dielectric compound which is represented by (RMbO3- δ)n(MaO)m and has a stratified triangular lattice structure, a compound containing R as the dielectric compound starting material, a compound containing Ma, and a compound containing Mb are mixed in order to prepare a starting material solution containing each of the elements, namely, R, Ma, and Mb (S101, preparation step); and a solid precursor of the dielectric compound is created from the starting material solution using a liquid phase method, such as coprecipitation (S102, liquid phase synthesis step). Then, the obtained solid precursor is heated at a prescribed calcination temperature in order to obtain a dielectric compound powder (S104, calcination step).
