The thermal shock and thermal fatigue behaviour of ceramic materials has been determined with a new type of testing system 3.
Thermal shock testing ceramics.
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.
Fired ceramic does not withstand thermal shock nearly as well as other materials like steel plastic wood etc.
The transition between temperature extremes occurs very rapidly greater than 15 c per minute.
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.
Ceramic is hard and resistant to abrasion but it is brittle and propagates cracks readily.
Thermal shock testing exposes products to alternating low and high temperatures to accelerate failures caused by temperature cycles or thermal shocks during normal use.
