Thermal Shock Testing Ceramics

Practical experience has shown that thermal shock tests do not lead to generally useful test data.

Thermal shock testing ceramics.

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. Thermal shock testing exposes products to alternating low and high temperatures to accelerate failures caused by temperature cycles or thermal shocks during normal use. 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. The thermal shock and thermal fatigue behaviour of ceramic materials has been determined with a new type of testing system 3.

Fired ceramic does not withstand thermal shock nearly as well as other materials like steel plastic wood etc. Ceramic is hard and resistant to abrasion but it is brittle and propagates cracks readily.
