Successful techniques for joining ceramics involve and rely on reactions at ceramic/metal interfaces for achieving strong and stable bonds. In fact, interfacial reactions can affect every stage of the formation of a joint from the onset of bonding to the development of equilibrated microstructure and the optimization of the mechanical properties. Reactive bonding of Si(3)N(4) using two established joining routes, brazing and diffusion bonding and a variant of these, partial transient liquid phase bonding has been studied. The systems evaluated are of brazing with V-active filler metals, diffusion bonding with FeCr alloy interlayers and partial transient liquid phase bonding with Pd/CuTi multilayer interlayers. The reactions that occur at the ceramic/metal interfaces of these systems, how they can be controlled and the ways in which the performance of the Si3N4 joints are affected discussed.
