SINTERED MATERIAL FOR DIELECTRIC SUBSTANCE AND METHOD FOR PRODUCING THE SAME, AND SINTERED MATERIAL FOR DIELECTRIC SUBSTANCE WHICH HAS CORE-SHELL FINE STRUCTURE AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a sintered material for a dielectric substance comprising a core-shell microstructure including a core of a first material and a shell of a second material, wherein a relative dielectric constant of the first material is larger than a relative dielectric constant of the second material.

SOLUTION: The sintered material for a dielectric substance includes a dispersed phase formed from a material selected from a group comprising NiO in which Li and Ti are doped, NiO in which Li and Al are doped, CuO, ACu3Ti4O12having a perovskite structure and RE2-yA'yNiO4and a continuous phase formed from a sintering aid, wherein A is 0COPYRIGHT: (C)2011,JPO&INPIT
