The theory of solid-state sintering is reviewed, with particular emphasis on the effects of several concurrent mechanisms on sintering behavior. Computer synthesis of both non-isothermal and isothermal sintering data has been used to predict initial sintering behavior under a wide variety of conditions. This approach has been successful in describing the sintering of compacts of spherical particles of Fe, Cu, Fe2 O3, Ag, and LiF. The relative importance of surface, grain boundary, and volume diffusion and vapor transport are discussed. Experimentally observed sintering behavior is discussed in terms of the theoretical model.
