Microwave Enhanced Diffusion,

Abstract

The observation of more rapid reaction and/or sintering during microwave processing of ceramics has lead to speculation that microwave processing results in 'enhanced diffusion' . The loss mechanisms by which microwaves interact with a crystal lattice have been reviewed. These mechanisms were evaluated with regard to the atomic theory of diffusion. The potential for these loss mechanisms to influence atomic diffusion, and thus produce enhancement will be discussed. Existing evidence, both direct and indirect, regarding microwave enhanced diffusion has been reviewed and will be discussed along with recent experimental data.
