The thermal shock of ceramic materials is influenced by many factors such as strength young s modulus fracture toughness thermal conductivity and thermal expansion coefficient.
Thermal shock testing ceramics.
Ceramic is hard and resistant to abrasion but it is brittle and propagates cracks readily.
The transition between temperature extremes occurs very rapidly greater than 15 c per minute.
This is probably due to the fact that thermal shock failure is a complicated function of the external thermal shock conditions and of the temperature functions of five different material properties.
The thermal shock and thermal fatigue behaviour of ceramic materials has been determined with a new type of testing system 3.
Practical experience has shown that thermal shock tests do not lead to generally useful test data.
The thermal shock fracture behavior of ceramics has been investigated using traditional testing methods such as the water quench in which the critical temperature difference where samples are.
