Abstract
A heat storage medium comprising a body of parent metal and an intrinsically cohesive ceramic layer formed integrally with the metal body and encapsulating said metal body is produced by the directed oxidation of a body of parent metal outwardly from the surface of said body to form integrally with the body of parent metal a layer of oxidation reaction product which encapsulates unreacted parent metal and forms a cavity resulting from the depletion of aprent metal.
