Science glossary film: Heat resistant

The ability of a substance to withstand the effects of high temperature without being permanently changed. Heat-resistant materials are essential for applications such as casting metals, and may be as simple as sand or ceramics, or as complex as the carbon fiber-reinforced silicon carbide used in the brakes of some racing cars.
