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过程介质。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。这赋予了MSHS许多不同寻常的特性，使它们与盐水或熔盐不同。MSHS可以在大气压下300摄氏度以上的温度下以液体形式存在，尽管有一定程度的湿度。MSHS还具有较高的热容和较大的水化热。这些特性表明，与水处理相比，这些特性具有更广泛的应用范围和更高的温度。尽管有这种令人兴奋的潜力，但熔盐水合物还没有进行过系统的研究。大多数已做的研究是零星的，探索了MSHS的几个方面和应用，但很少有实际说明
