Abstract
Melting points of some kinds of molten salts have been determined, and also supercooling characteristics of potassium thiocyanate KSCN and calcium chloride CaCl2 have been investigated. Molten salt has been utilized as a thermal storage material, cooling material for the nuclear reactor, refinement of the petroleum, fuel battery, molten-salt reactor because of its excellent thermal characteristics and chemical stability. Therefore, it is important for its utilization to store the data of thermophysical properties to control both the melting and solidification processes. The sample of molten salt is both heated and cooled depending on the prescribed heating-cooling temperature curves in the electric furnace with a controller. The melting points were determined as the constant temperatures which can be observed for some period in the cooling process. Furthermore, the supercooling characteristics were investigated under various sample masses and cooling rates as parameters. It was found that the degree of supercooling depended closely on both the cooling rate and the sample mass.
