Abstract
A dielectric material with heat transfer properties includes a first fluid and a second fluid different from the first fluid and miscible with the first fluid. The first fluid and the second fluid are mixed with each other so as to form a mixture and are kept at a temperature and a pressure so that the mixture is maintained in a supercritical phase. The mixture has at least one parameter that is preferably different from a corresponding parameter in both a supercritical phase of the first fluid and a supercritical phase of the second fluid. In a method of insulating electrical contacts and removing heat therefrom, the mixture is disposed about the electrical contacts and is maintained at a temperature and at a pressure that causes the mixture to be in a supercritical phase so that the mixture has favorable dielectric and heat transfer properties.
