Reactions in Solid Phase-I

Abstract

The chemical reactivity in solids results form imperfections in electronic distribution in bands and point or line imperfections in atomic arrangement. The case with which these imperfections are formed and move within the crystal influences the speed of the reactions. The properties of these imperfections are derived from the study of electronic and ionic conductivity, spectroscopy, X-ray diffraction and luminescence. With precise information about the nature of defects it is possible to control the reactivity of solids. The importance of these studies in extending the knowledge of solids state and in improving industrial applications has been highlighted.
