ABSTRACT:
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.
