Corrosion of High-Performance Ceramics

"Corrosion of High-Performance Ceramics" is a comprehensive
survey of the state of the art of this new field of
research. It presents the first generalized description of
the corrosion of engineering ceramics and its effect on
their mechanical properties (based on Si3N4, SiC, AlN, B4C,
BN, Al2O3, ZrO2).
Researchers, engineers and graduate students are provided
with a guide to the performance of non-oxide and oxide
ceramicsin corrosive environments.
Keywords: high-temperature oxidation; hot corrosion;
corrosion in acids, alkalis and molten salts; effects of
corrosion on the physico-mechanical properties of ceramics;
stress corrosion; corrosion protection; development of
oxidation-resistant ceramics; role of purity, donations and
microstructure.
