What Is the Melting Point of Salt?

The melting point of sodium chloride, commonly referred to as table salt, at standard pressure is 801 degrees Celsius. This represents the phase transition from solid, crystalline salt to a liquid. Liquid salt turns to a gas, or boil, at 1,413 degrees Celsius.

Solid salt is found abundantly throughout the surface of the Earth and is represented significantly in the salinity of the world’s oceans. Salt comes from a variety of sources, including mining rock salt and desalinating ocean water. Approximately 270 million metric tons of salt are produced worldwide annually; China leads globally with 60 million metric tons produced.
