Corrosion behaviour of different technical ceramics in acids, basic solutions and under hydrothermal conditions

The corrosion behaviour of different technical ceramics (SSiC, LPS SiC, GPSN, PSZ, TZP, ZTA and alumina) was investigated in acids, bases and under hydrothermal conditions. Besides the mass loss data, the residual strength and the thickness of the corroded layers were used for the characterisation of the corrosion intensity. Investigations in acids, bases and under hydrothermal conditions show that the stability of the materials strongly depends on the composition and the corrosive medium.
