Theory of Microwave Interactions with Ceramic Materials,
Abstract
Very little is known about how microwaves interact with ceramics. We have recently developed a theory of these processes on the basis of Debye relaxation of interstitials, vacancies and bivacancies, and explained successfully thermal runaway observations on silica, alumina, strontium titanate, zinc oxide and iron oxide, as well as dielectric constant and loss factor observations on alumina, silica, and boron nitride. The article addresses these results as well as their satisfactory correlation with potentials for atomic motion and diffusion barriers obtained on the basis of ab initio computer calculations, and our recent exploration of structure effects on the phenomena of thermal runaway and microwave absorption.
