Molten-salt reactors are a type of nuclear reactor that uses molten salt(s) as a coolant or as a solvent in which the fissile material is dissolved. 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]
In the technical terms of physical chemistry, the minimum freezing point of a water-salt mixture is −21.12 °C (−6.02 °F) for 23.31 wt% of salt. Freezing near this concentration is however so slow that the eutectic point of −22.4 °C (−8.3 °F) can be reached with about 25 wt% of salt.
Trends in melting points can be even better explained when the structure and ionic size ratio is taken into account. [62] Above their melting point, salts melt and become molten salts (although some salts such as aluminium chloride and iron(III) chloride show molecule-like structures in the liquid phase). [63]

Sodium chloride, also known as 'edible salt' or 'table salt' [87] (chemical formula NaCl), is the principal source of sodium (Na) in the diet and is used as seasoning and preservative in such commodities as pickled preserves and jerky. For Americans, most sodium chloride comes from processed foods. [88]
Both table salt and sea salt share a similar makeup, containing roughly 40 percent sodium by weight. One thing to be mindful of: Because table salt tends to be finer textured, the same volume of ...
Edible salt is sold in forms such as sea salt and table salt, the latter of which usually contains an anti-caking agent and may be iodised to prevent iodine deficiency. As well as its use in cooking and at the table, salt is present in many processed foods. Sodium is an essential element for human health via its role as an electrolyte and ...
Ice has a semi-liquid surface layer; When you mix salt onto that layer, it slowly lowers its melting point. The more surface area salt can cover, the better the chances for melting ice.
