Composite sintered body, honeycomb structure, electrically heated catalyst, and method for producing composite sintered body
The invention relates to a composite sintered body, a honeycomb structure, an electrically heated catalyst, and a method for manufacturing the composite sintered body, and aims to improve the oxidation resistance of the composite sintered body. The composite sintered body includes a silicon phase, a cordierite phase, and a high-resistance silicon carbide phase. The content of silicon in the composite sintered body is from 30% by mass to 50% by mass (inclusive) with respect to the composite sintered body. The content of cordierite in the composite sintered body is from 10% by mass to 50% by mass (inclusive) with respect to the composite sintered body. The content of the high-resistance silicon carbide in the composite sintered body is from 20% by mass to 50% by mass (inclusive) with respect to the composite sintered body. Therefore, the silicon particles can be coarsened, and the oxidation resistance of the composite sintered body can be improved.
