Most ceramic materials are sensitive to thermal shock and thermal fatigue. Due to inhomogeneous temperature distributions in rapidly cooled or heated ceramic components, high thermal stresses are generated which are responsible for the extension of existing cracks. Whereas in metals the temperature gradients only cause small plastic deformations, in the case of ceramics with its linear elastic material behaviour high stresses are generated. As a consequence, thermal stresses have to be avoided or at least to be minimized by an appropriate design or an appropriate material selection.
