Abstract
Abstract Inorganic adhesives suitable for bonding metals to metals, metals to ceramics, or ceramics to ceramics with high bonding strength are disclosed, which contain a composite mechanical alloy powder comprising: (a) from about 10 to 60 wt % of particles of at least one of Cu and Ni; (b) from about 10 to 80 wt % of particles of at least one of Ti, Nb, and Zr; and (c) from about 10 to 80 wt % of Ag particles. The composite powder can be dispersed in an organic solvent to form a paste adhesive.
