Abstract
Composition comprising (a) susceptors having the capability of absorbing microwave energy, and (b) a matrix substantially non-reflective of microwave energy. The susceptors comprise a particulate substrate having a thin-film coating thereon. The particulate substrate is substantially non-reflective of microwave energy and the coating is capable of absorbing microwave energy. The matrix typically comprises polymeric or ceramic materials that are stable at temperatures conventionally used in microwave cooking. The composition allows reuse of the susceptors, eliminates decline in heating rate, eliminates arcing, allows the heating rate to be controlled, allows overheating to be controlled, and allows formation of microwave heatable composite materials having very low metal content.
