PROBLEM TO BE SOLVED : To provide a perovskite-based black powder that is a composite oxide having a perovskite type crystal structure comprising an inorganic material including constituent elements of three or more and is softer than powder obtained by a dry production method and has a markedly large primary grain diameter compared with powder obtained by a conventional wet precipitation production method and has a primary grain diameter that is allowed to grow crystals to 1 μm or more and is a material excellent in functionalities, and to provide a method for producing the powder.SOLUTION : There are provided a perovskite-based black powder, a method for producing the perovskite-based black powder, and a resin composition in which the perovskite-based black powder is dispersed and contained. The perovskite-based black powder is a composite oxide that comprises, as constituent elements, rare earth elements and/or alkaline earth metal elements and any element selected from Cr, Mn and elements of groups 8 in the periodic table, and has a flexible crystal structure of perovskite type comprising at least three kinds of elements or a comparable type thereof, and has a primary grain diameter that is allowed to grow crystals to 1 μm or more.SELECTED DRAWING : NoneCOPYRIGHT : (C)2017, JPO&INPIT
