Abstract Provided is a dielectric material for ceramic capacitors which has low temperature dependence and a high relative dielectric constant. Provided are: a dielectric material for ceramic capacitors, characterized by comprising a composite oxide powder that has a garnet-type or garnet-like crystal structure which contains essential elements Li, La, Zr, and O, having Li site vacancies that are obtained by substitution of a portion of the essential elements with an additive element which differs from the essential elements, and having an ion conductivity at room temperature of at least 1×10-5 S/cm; and a dielectric material for ceramic capacitors obtained by sintering the dielectric material. L'invention concerne un matériau diélectrique pour condensateurs céramiques qui présente une faible dépendance à la température et une constante diélectrique relative élevée. L'invention concerne : un matériau diélectrique pour des condensateurs céramiques, caractérisé en ce qu'il comprend une poudre d'oxyde composite qui a une structure cristalline de type grenat ou similaire grenat qui contient les éléments essentiels Li, La, Zr, et O, ayant des vides de sites Li qui sont obtenus par substitution d'une partie des éléments essentiels avec un élément additif qui diffère des éléments essentiels, et ayant une conductivité ionique à température ambiante d'au moins 1×10-5 S/cm ; et un matériau diélectrique pour des condensateurs céramiques obtenus par frittage du matériau diélectrique. 温度度依存性が低く、比誘電率が高いセラミックコンデンサ用誘電体材料を実現する。 Li、La、Zr、及びOの各必須元素を含むガーネット型又はガーネット型類似の結晶構造を有する複合酸化物の粉末からなり、前記必須元素の一部が該必須元素と異なる添加元素で置換されてLiサイト空孔を有しており、室温におけるイオン伝導率が1×10-5S/cm以上であることを特徴とするセラミックコンデンサ用誘電体粉末であり、これを焼結してなるセラミックスコンデンサ用誘電体材料である。
