Abstract:
A method of forming a brazed joint between a first alumina-ceramic part and a second alumina-ceramic part, comprising the steps of:applying to a joint formed by said first alumina-ceramic part and said second alumina-ceramic part an active brazing solder consisting essentially of 8.6 wt. % to 12 wt. % titanium, 1 wt. % to 8 wt. % beryllium, 0 wt. % to 16.5 wt. % iron, 63.5 wt. % to 90.4 wt. % zirconium, and a remainder being any impurities; heating said active brazing solder applied to said joint to a brazing temperature in order to melt said active brazing solder and wet said first alumina-ceramic part and said second alumina-ceramic part with said active brazing solder; and cooling said active brazing solder after said heating step to an ambient temperature to form said brazed joint between said first alumina-ceramic part and said second alumina-ceramic part.
