Corrosion Resistance of Structural Ceramics in Aqueous Environments

Abstract

Corrosion behavior of structural ceramics in aqueous environments, such as high-temperature high-pressure water and steam, and acidic and basic aqueous solution, are reviewed. These environments lead to three main types of chemical corrosion: dissolution of grain boundary phase, reaction of ceramic grains, and water-induced phase transformation. Corrosion resistance of structural ceramics are discussed from the microstructure resulting from ceramic processing.
