Provided are a brazing material in paste form containing a powder mixture that contains titanium powder having an average particle diameter (D50) of 20 μm or less in an amount of 0.7 to 2.0 mass %, copper powder in an amount of 3 to 15 mass %, and silver powder as the remaining portion, and a vehicle, and techniques associated with the brazing material.

Brazing material, method for producing the same, and method for producing metal-ceramics bonded substrate

After a copper plateis bonded to at least one surface of a ceramic substratevia an active metal containing brazing filler metalwhich contains silver, the unnecessary portion of the copper platand active metal containing brazing filler metalis removed, and thereafter, an unnecessary portion of the copper plateis removed by chemical polishing so as to cause the active metal containing brazing filler metalto protrude from the side face portion of the copper plate, and then, a silver layeradhered to the surface of the copper plateby the chemical polishing is removed.
