SODIUM (MOLTEN) Chemical compatibility with O-rings, rubbers, & plastics

Molten Sodium is a highly reactive, silvery metal in its liquid state, commonly used in various industrial and chemical applications. It is produced by heating solid sodium to its melting point of 97.8°C (208°F). Molten Sodium is widely used as a coolant in fast breeder nuclear reactors due to its excellent thermal conductivity and ability to transfer heat efficiently. It is also employed in the production of certain chemicals, such as sodium compounds and sodium-based catalysts. In metallurgy, Molten Sodium is used for the reduction of metals from their ores and as a flux in certain welding and brazing processes. Proper handling and storage of Molten Sodium are essential to prevent accidents and ensure safety, as it is highly reactive and can ignite spontaneously upon contact with air or water. Proper safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are essential when working with Molten Sodium. Its unique properties make Molten Sodium a valuable chemical in various industrial and chemical applications.
