Molten Salt Hydrates (MSHs) are promising media for chemical metallurgical processes. These are highly concentrated salt solutions, for example, molten FeSO4-7H2O or CaCl2-4H2O where the polar water molecule is bound to the salt. This gives MSHs a number of unusual properties that put them in a different class than brines or molten salts. MSHs can exist as liquids at temperatures above 300oC at atmospheric pressures, albeit with some level of humidity. MSHs also have both a high heat capacity and a large heat of hydration. These properties suggest diverse applications and at higher temperatures compared to those in aqueous processing. Despite this exciting potential, molten salt hydrates have had no systematic study. Most of the research that has been done is sporadic, exploring a few aspects and applications of MSHs with little actual elucidation of
