Reaction between structure elements in the solid state

Reaction between structure elements in the solid state 

This reaction produces or consumes vacancies or ions within the interstitial position at the interface between a solid phase and another solid or gaseous phase, such as those found at an oxide-metal interface during the oxidation of zinc by oxygen. This can be written using Kroger s notation (see Appendix 1)  

Reactions between adsorbed species and point d ects 

The wide variety of elementary reactions hitherto exarrrined is far from covering all possible stages. Insufficient experimental data often result in researchers settling for hypotheses that are compatible with the overall process of the reactioa Often, 

A step during which two intermediates react with each other is sometimes called a quadratic step.
