Thermal Shock Resistance Of Ceramics

Heat and thermal shock resistance.

Thermal shock resistance of ceramics. Thermal shock is a type of rapidly transient mechanical load by definition it is a mechanical load caused by a rapid change of temperature of a certain point. Thermal shock of ceramics free download as word doc doc pdf file pdf or read online for free. Thermal shock resistance refers to the material s ability to withstand extreme and rapid changes in temperature. A method of quantifying thermal shock resistance the hasselman parameters is.

This is a process that takes place abruptly when there is a sudden variation of temperature either from hot to cold or vice versa. The heat resistant properties of fine ceramics are measured by the temperatures at which they begin to melt and by their levels of thermal shock resistance. Thermal gradients are also described and the properties and conditions needed for thermal shock resistance are identified. It can be also extended to the case of a thermal gradient which makes different parts of an object expand by different amounts.

Thermal shock resistance refers to a material s ability to withstand rapid changes in temperature. Ceramic materials have a very high melting point and are less resistant to thermal shock. It frequently causes breakage in the material and is most common in brittle materials such as ceramics. This paper defines thermal shock and discusses why thermal shock is important in ceramics.

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