Question

Which specific ceramics have the best thermal shock resistance ?

Answer 1

Answer:

Thermal shock can be prevented by:

Avoiding sudden temperature changes.

Increasing the structural strength of the material.

Enabling the material to conduct heat more efficiently, causing a more even expansion or contraction when encountering temperature changes.

Thermal shock occurs when a thermal gradient causes different parts of an object to expand by different amounts. This differential expansion can be understood in terms of stress or of strain, equivalently. At some point, this stress can exceed the strength of the material, causing a crack to form.
