- the firing temperature program was as follows: in a nitrogen atmosphere of 0.1 MPa, the temperature was increased from room temperature to 10 ° C./min, heated to 1200 ° C., held at this temperature for 2 hours, and then the nitrogen atmosphere pressure in the furnace Was changed to 0.9 MPa, and the temperature was further increased at a rate of 10 ° C./min to 1800 ° C. After this temperature was maintained for 6 hours and heat treatment was performed, the temperature was lowered at a rate of 5 ° C./min and cooled to room temperature. In this way, a silicon nitride ceramic joined body was obtained.
- the silicon nitride ceramic joined body to which a load of 0.02 MPa was applied by a weight in a firing furnace was heated to 1800 ° C. in the atmosphere at a rate of 10 ° C./min from room temperature. This temperature was maintained for 6 hours and heat treatment was performed, and then the temperature was lowered at a rate of 5 ° C./min to cool to room temperature. Thus, the silicon nitride ceramic joined body of Example 2 was obtained.
- a test piece was cut out by grinding so that the joining surface was located at the center.
- this test piece was used to measure the bonding strength based on the four-point bending strength at room temperature according to JIS R1601, a bonding strength of 560 MPa was shown.
- the four-point bending strength of the silicon nitride ceramic simple substance that is the material to be joined is 750 MPa.
- Example 1 In Example 1, the layer made of metallic aluminum was not fixed to the bonding surface of the materials to be bonded. Except this, the same operation as in Example 1 was performed. However, the alumina ceramics that are the materials to be joined cannot be joined together.
- Example 2 a layer made of metal silicon powder was not formed on each surface of a sheet-like molded body made of a mixed powder obtained by adding each powder of yttria and alumina to silicon nitride powder. Except this, the same operation as in Example 2 was performed. However, it was not possible to join silicon nitride ceramics, which are materials to be joined.
