CERAMIC CAPACITOR DIELECTRIC MATERIAL
PROBLEM TO BE SOLVED: To provide a ceramic capacitor dielectric material stabilizing effects of temperature on electrostatic capacitance and effects of electric field on electrostatic capacitance and fitting to X7T dielectric properties of EIA.SOLUTION: There is provided a ceramic capacitor dielectric material manufacturing a dielectric material by mixing BaTiO3 with added amount 40 to 80 mol%, BaZrO3 with added amount of 20 to 40 mol% and SrTiO3 with added amount of 20 mol% or less as main components, MgCO3, SiO2 and one or more kind of compound selected from a compound of transition metal or a compound of rare earth element. A temperature at Curie point is reduced to a room temperature or less by adding BaZrO3 and stable cubic crystal structure is formed and stability of dielectric property to temperature can be enhanced by stability of a crystal structure. There is provided a ceramic capacitor dielectric material containing MgCOof 2 to 6 mol% and SiOof 2 mol or less.SELECTED DRAWING: Figure 1
【課題】温度が静電容量に与える影響及び電場が静電容量に与える影響を安定させ、ＥＩＡのＸ７Ｔ誘電特性に適合するセラミックコンデンサ誘電体材料を提供する。【解決手段】主成分としての、添加量４０−８０ｍｏｌ％のＢａＴｉＯ３、添加量２０−４０ｍｏｌ％のＢａＺｒＯ３、及び添加量２０ｍｏｌ％以下のＳｒＴｉＯ３と、ＭｇＣＯ３、ＳｉＯ２、及び遷移元素の化合物または希土類元素の化合物から選択される１種以上の化合物と、を混合して、誘電体材料を製造するセラミックコンデンサ誘電体材料。ＢａＺｒＯ３を添加することでキュリー点の温度を室温以下に下げて、安定した立方晶構造を形成し、結晶構造の安定により誘電性の温度に対する安定性を高めることができる。ＭｇＣＯ３が２〜６ｍｏｌ％とＳｉＯ２が２ｍｏｌ以下であるセラミックコンデンサ誘電体材料。【選択図】図１
