Title:
METHOD FOR MANUFACTURING CERAMICS JOINED BODY
Document Type and Number:
Japanese Patent JP2013082170
Kind Code:
A
Abstract:

To provide a method for manufacturing a ceramics joined body that can control causing crack or peeling to the joint after the sintering.

The method for manufacturing ceramics joined body 3 includes: processes (S10, S20) that individually form first and second ceramic formed bodies 1 and 2 that comprise mutually the similar materials; a process (S30) that forms the ceramics joined body 3 by fitting the first and second ceramic formed bodies 1 and 2 by using the isostatic pressing; and a process (S40) that sinters the ceramics joined body 3. Each forming pressure when the first and second ceramic formed bodies 1 and 2 are individually formed is lower than the forming pressure of the isostatic pressing. The forming pressure of the first ceramic formed body 1 when the first and second ceramic formed bodies 1 and 2 are individually formed is lower than the forming pressure of the second ceramic formed body 2. The second ceramic formed body 2 is fitted in the first ceramic formed body 1 and the ceramics joined body 3 is obtained in the isostatic pressing.
