  • Patent number: 8871661
    Abstract: Provided is a bonding material which can bond base materials or substrates having different linear thermal expansion coefficients, and can have heat resistance against temperatures of 300° C. or higher, vacuum airtightness and bonding strength, further which has excellent handleability and workability. The bonding material is produced by mixing, in a content ratio of 0.01 to 60 mass % (to the whole), a metal Ga, and/or at least one metal or alloy powder selected from the group consisting of a metal powder mixture of a combination of Bi and Sn or an alloy powder thereof, and a metal powder mixture of a combination of Bi, Sn and Mg or an alloy powder thereof with a Bi2O3-based glass frit powder having an average particle diameter of 200 ?m or less. The bonding material may be formed in a paste form by adding a solvent thereto. This feature makes it possible to bond together substrates having different thermal expansion coefficients without causing a crack or unsticking.
