Eutectic salts are a type of salt mixture that exhibit unique properties, such as low melting points and high thermal stability. These salts are derived from a eutectic mixture, which is a combination of two or more salts that melt at a lower temperature than any of the individual components. Eutectic salts have gained attention for their potential applications in thermal energy storage, as they can store and release heat energy efficiently. They are also being researched for their use in molten salt reactors, as well as in various chemical and industrial processes. Eutectic salts have the potential to play a key role in sustainable energy technologies and are an area of ongoing research and development.
