Method of producing an active brazing paste

摘要

To produce an active brazing paste suitable for brazing leads in insulating parts, e.g., ceramic parts, and containing an active brazing powder and an organic material acting as a vehicle, coarse pieces of the active brazing alloy are prehydrogenated. These pieces are ground in a mill with the addition of hydrogen to form a hydrogenated active brazing powder. The latter is then processed with the liquid vehicle openly, under normal atmospheric and temperature conditions, to form the active brazing paste.
