The product layer sequence in the reaction of solid Ti with alumina and in the reaction of Ti dissolved in liquid Ag with alumina are compared. The phase diagram and the diffusion path in the Ti-Al-O system are used to describe the interface formation during brazing of alumina with liquid Ag-4 wt.% Ti filler material. During brazing, first Ti-Al(O) intermetallics are formed. When the filler material is depleted from Ti, the formed Ti-Al(O) intermetallics decompose in oxygen saturated Ti(O) and Al, which in turn diffuses through the Ti(O) and dissolves in the Ag.
