Thermal Shock Resistant
Definition - What does Thermal Shock Resistant mean?
A material that is thermal shock resistant has the ability to resist rapid and sudden changes in temperature.
Thermal shock in a material occurs when the temperature or thermal gradient causes random expansions at various points within the material. This creates areas of stress and strain acting on the material while in operation, rendering it susceptible to fracturing and potentially unsafe.
Corrosionpedia explains Thermal Shock Resistant
A material with high thermal shock resistance is able to withstand wide temperature variations. The stresses generated are determined by multiplying Young's modulus, the coefficient of thermal expansion, and the temperature difference between the interior and the surface of the material.
Silicon nitride is a superior material that displays very high thermal shock resistance when it is heated to 550°C (1,022°F) and then cooled rapidly by putting it in water. This quality of silicon nitride makes it a preferred material for the metal manufacturing and energy generation industries.
