Nanometer molten salt heat-transfer and heat-storage medium, preparation method and use thereof

摘要

The present invention provides a nano molten salt heat transfer and heat storage medium, the method of preparation and the application, which belongs to the technical sector of heat storage and transfer. The nano molten salt heat transfer and heat storage medium of the invention means that the metal oxide nano-particles and/or non-metal oxide nano particles are dispersed in the conventional molten salt system to form the nano molten salt heat transfer and heat storage medium by composition. The heat transfer and heat storage medium provided by the invention has the good thermal stability and high thermal conductivity, which is ideally suited for industrial energy storage, thermal storage and transfer system of solar thermal power generation.
