Dielectric powder for ceramic capacitor and ceramic capacitor using same
The dielectric material for the ceramic capacitor is low in temperature dependency and high in relative dielectric constant. A dielectric powder for a ceramic capacitor and a dielectric material for a ceramic capacitor obtained by sintering the same, the dielectric powder being characterized by comprising a powder of a composite oxide having a garnet-type or garnet-like crystal structure containing each essential element of Li, La, Zr, and O, a part of the essential element is substituted by an additive element different from the essential element, so that the electrolyte has a Li site vacancy, and the ionic conductivity at room temperature is 1 * 10 <-5 > S/cm or more.
本发明实现一种温度度依存性低、相对介电常数高的陶瓷电容器用介电体材料。一种陶瓷电容器用介电体粉末、将其烧结而成的陶瓷电容器用介电体材料，其特征在于，包括具有包含Li、La、Zr、及O各必需元素的石榴石型或类似石榴石型的结晶结构的复合氧化物的粉末，所述必需元素的一部分被与所述必需元素不同的添加元素置换，而具有Li位点空位，室温下的离子传导率为1×10‑5S/cm以上。
