Molten salt

As a reference, molten sodium chloride, table salt has a melting point (m.p.)

[7] Molten salts (fluoride, chloride, and nitrate) can be used as heat transfer fluids as well as for thermal storage.

Experimental salts using lithium can be formed that have a melting point of 116 °C while still having a heat capacity of 1.54 J/(g·K).

[4] Molten chloride salt mixtures are commonly used as quenching baths for various alloy heat treatments, such as annealing and martempering of steel.

Cyanide and chloride salt mixtures are used for surface modification of alloys such as carburizing and nitrocarburizing of steel.
