CERAMIC BODY AND HEATER ELEMENT
To provide a ceramic body having such PTC characteristics that the electric resistance at a room temperature is moderately high, and the resistance temperature coefficient between a room temperature and 200°C is also high.SOLUTION: A ceramic body 100 comprises a ceramic which accounts for 90 mass% or more and which has the following compositional formula: (Ba1-x-yA1xA2y)TiO3 (where A1 represents one or more kinds of rare earth elements, A2 represents one or more kinds of alkali metal elements, 0.001≤x≤0.01, 0.001≤y≤0.01 and 0.002≤x+y≤0.02).SELECTED DRAWING: Figure 1
【課題】室温での電気抵抗が適度に高く、室温と２００℃の間の抵抗温度係数も高い、ＰＴＣ特性を有するセラミックス体を提供する。【解決手段】組成式が（Ｂａ1-x-yＡ１xＡ２y）ＴｉＯ3（式中、Ａ１は一種又は二種以上の希土類元素を表し、Ａ２は一種又は二種以上のアルカリ金属元素を表し、０．００１≦ｘ≦０．０１、０．００１≦ｙ≦０．０１、０．００２≦ｘ＋ｙ≦０．０２である。）で表されるセラミックスが９０質量％以上を占めるセラミックス体１００。【選択図】図１
