Abstract
A composite body of the present invention includes a base and an oxide layer arranged on the base, the oxide layer containing more than 45% by volume of a perovskite-type oxide phase. The composite body may include a first member, a second member, and a joining portion that joins the first member and the second member, at least one of the first member and the second member serving as the base, and the joining portion serving as the oxide layer. The composite body may include the base and a covering portion that covers the whole or part of a surface of the base, the covering portion being formed of the oxide layer.
Claims15
A composite body comprising:
- a honeycomb structure;
- a first member;
- a second member;
- and
- a joining portion that joins the first member and the second member,
- wherein at least one of the first member and the second member serves as a base, the joining portion is an oxide layer containing 70% or more by volume of a perovskite-type oxide phase, the base is formed on an outer circumferential surface of the honeycomb structure, and the joining portion is formed on an outer surface of the base.
A method for producing a composite body comprising a honeycomb structure, comprising a step of:
- firing a laminate including a joining portion raw material arranged between a first member and a second member to form a joining portion that joins the first member and the second member,
- wherein at least one of the first member and the second member serves as a base, the joining portion is an oxide layer containing 70% or more by volume of a perovskite-type oxide phase, the base is formed on an outer circumferential surface of the honeycomb structure, and the joining portion is formed on an outer circumferential surface of the honeycomb structure.
