    • PROBLEM TO BE SOLVED: To more satisfactorily disperse the additional component of a ceramic precursor into the main component. 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.

    • 要解决的问题:为了使陶瓷前体的附加成分更均匀地分散到主要成分中。 解决方案:原子构型陶瓷可以通过配位具有易配位的部分22的配位体21,其可以配位成作为主要成分的组分和作为附加组分的ab组分和难以配位的部分23 其与a组分和b组分的偶联被抑制到组分和b组分中,以便产生复合配体24和ab络合配体25,加入离子或包含交联组分的络合物,其可以偶联 具有两个或多个难以配位的部分23(交流部件26)至包含络合配体24和b络合配体25的溶液,以便产生前体28并在温和条件下烧制所制备的前体28。 在制备前体28时,在b络合配体25中,互不耦合部分被几乎不配合的部分23抑制,并且c部件位于它们之间,因此不会发生作为附加部件的b成分相邻的现象 并且能够充分地抑制b成分的相邻存在。 版权所有(C)2010,JPO&INPIT
