<P>PROBLEM TO BE SOLVED: To more satisfactorily disperse the additional component of a ceramic precursor into the main component. <P>SOLUTION: The atom-configurated ceramic can be obtained by coordinating a ligand 21 having an easily coordinatable part 22 which can be coordinated into an a component as the main component and a b component as an additional component and a hardly coordinatable part 23 in which the coupling with the a component and the b component is suppressed into the a component and the b component, so as to produce an a complex ligand 24 and a b complex ligand 25, adding an ion or a complex comprising a c component which can be coupled with two or more hardly coordinatable parts 23 (a c component 26) to a solution comprising the a complex ligand 24 and the b complex ligand 25, so as to produce a precursor 28 and firing the produced precursor 28 under mild conditions. Upon the production of the precursor 28, in the b complex ligands 25, mutual coupling is suppressed by the hardly coordinatable parts 23, and the c component lies therebetween, thus the phenomenon that the b components as an additional component are made adjacent does not occur, and the adjoining presence of the b components can be sufficiently suppressed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
