Ceramic metal bonding material and method for manufacturing ceramic metal bonding material using the same and vacuum airtight container made using the same

摘要

The present invention relates to a ceramic metal bonding material capable of forming a highly reliable sealing portion with good reproducibility by preventing diffusion of elements from a sealing port to a brazing material in the sealing of a simple vacuum hermetic container using an active metal method and a ceramic metal bonding material And a vacuum airtight container using the same.;An active metal brazing material 3 disposed on the side of the insulating container 5 made of a ceramic member and a metal brazing material 1 disposed on the side of the sealing member 4 made of a metal member and these brazing materials 1 and 3 (2) for preventing the diffusion of the constituent elements of the metal member, and is suitable for a sealing member for vacuum hermetic containers. The vacuum hermetic container is obtained by sealing the opening of the insulating container 5 made of a ceramic member with a sealing member 4 made of a metal member by using the sealing member for the vacuum hermetic container.
