    摘要: A bonded, boron carbide-containing ceramic body includes ceramic members. These ceramic members each contain boron carbide at 2 mass % or higher, and are integrated together via a bonding layer bonded with a bonding material containing at least one metal selected from the group consisting of aluminum, copper, gold and zirconium or integrated together via a bonding layer formed from one of aluminum metal and an aluminum compound and a titanium compound as bonding materials, wherein a bonded part has a strength of 100 MPa or higher. According to this technology, the boron carbide-containing ceramic members can be bonded together with a high strength of 100 MPa or more by a simple process, and further, the bonding is feasible with excellent chemical resistance at the bonded part as needed.
