Thermal Shock Resistance Of Ceramics Materials

Thermal shock resistance refers to the material s ability to withstand extreme and rapid changes in temperature.

Thermal shock resistance of ceramics materials.

Melting of ceramics at high temperature involve a thermal shock during cooling and this will require a high temperature preheating of the powder bed to prevent thermal shock from the cooling of the melt pool from high temperature to lower temperatures. The thermal shock of ceramic materials is influenced by many factors such as strength young s modulus fracture toughness. Concepts and theories as well as typical experimental results on thermal shock resistance of ceramic materials are reviewed with an emphasis on the hasselman theory. Silicon nitride a particularly heat tolerant material displays superior resistance to thermal shock as tested by heating the material to 550 1 022 and then rapidly cooling it by dropping it into water.

On the basis of the strain energy concept in the latter half of this paper a new thermal shock test method for refractory firebricks is introduced.

These temperature fluctuations cause thermal stresses in the ceramic and consequently the propagation of micro cracks that permanently damage the material.
