Corrosion behaviour is one of the most poorly understood characteristics of ceramics. In this text a balanced mixture of scientists from material science, metallurgy, physics, chemistry and mineralogy sum up the state of the art of measurement and modelling and reveal future research directions. The book reviews the theory of corrosion of ceramics, including the diffusion of gases and the predictions of thermodynamics. It discusses critically the kinetic models and representation tools for layer growths and material destruction. Corrosion of nitrides, carbides and oxides by simple and complex gases (O2, H2O, SO2 halides) and melts (ionic and metallic) reveal current measurement and modelling methods, advanced experimental techniques, such as laser diagnostics, TV holography, Raman spectroscopy and NDE surface methods. Frontier areas (such as, the modelling of porous materials corrosion and protection) are revealed. The text is suitable for scientists and engineers in materials science, dealing with ceramics and their application. It should also be useful for research students, solid state physicists and physical chemists.
