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

熔盐水合物（MSHs）是一种很有前途的化学冶金介质。这些是高度浓缩的盐溶液，例如熔融的FeSO4-7H2O或CaCl2-4H2O，其中极性水分子与盐结合。这使msh具有许多不同寻常的性质，使其与卤水或熔盐不同。在大气压下，MSHs可以以液体的形式存在，温度高于300摄氏度，尽管有一定程度的湿度。msh还具有高的热容量和大的水化热。与水处理相比，这些特性具有不同的应用和更高的温度。尽管有这种令人兴奋的潜力，熔盐水合物还没有系统的研究。目前所做的研究大多是零星的，对MSHs的几个方面和应用进行了探索，实际的阐述很少
