COMPOSITE SINTERED BODY, HONEYCOMB STRUCTURE, ELECTRIC HEATING CATALYST, AND MANUFACTURING METHOD OF COMPOSITE SINTERED BODY
To provide a composite sintered body having low resistance and high oxidation resistance.SOLUTION: A composite sintered body includes a silicon phase as a main phase, a cordierite phase, and an amorphous phase containing Si. Also, the volume resistivity at room temperature is 0.1 Ω cm or more and 2.5 Ω cm or less. As a result, even when the composite sintered body is exposed to a high-temperature oxidizing atmosphere, oxidation of the silicon particles is suppressed, and a change in volume resistivity of the composite sintered body is suppressed. Therefore, it is possible to provide a composite sintered body having low resistance and high oxidation resistance (that is, having a small rate of change in resistance after being exposed to a high-temperature oxidizing atmosphere).SELECTED DRAWING: Figure 1
【課題】低抵抗であって、かつ、高耐酸化性を有する複合焼結体を提供する。【解決手段】複合焼結体は、主相であるシリコン相と、コージェライト相と、Ｓｉを含む非晶質相とを含む。また、室温における体積抵抗率は０．１Ω・ｃｍ以上かつ２．５Ω・ｃｍ以下である。これにより、複合焼結体が高温酸化雰囲気に曝露された場合であっても、シリコン粒子の酸化が抑制され、複合焼結体の体積抵抗率の変化が抑制される。したがって、低抵抗であって、かつ、高耐酸化性を有する（すなわち、高温酸化雰囲気下に曝露された後の抵抗変化率が小さい）複合焼結体を提供することができる。【選択図】図１
