Abstract
This invention discloses novel compositions of matter, in particulate forms, which function as heat transfer agents for heating or cooling applications. The particulates comprise solid carriers containing microwave responsive substances which are liquid at a predetermined elevated operating temperature. These particulate agents, preheated by microwave energy, serve as sources of dry heat or moist heat, depending on their composition. They also serve as sources of cold, when prechilled in a freezer.
