FLiNaK
FLiNaK is the name of the ternary eutectic alkaline metal fluoride salt mixture LiF-NaF-KF (46.5-11.5-42 mol %).〔http://www.energyfromthorium.com/pdf/FFR_chap12.pdf Lane, James A. Fluid Fuel Reactors. Reading, MA: Addison-Wesley Pub, 1958, p. 570〕 It has a melting point of 454 °C and a boiling point of 1570 °C. It is used as electrolyte for the electroplating of refractory metals and compounds like titanium, tantalum, hafnium, zirconium and their borides. FLiNaK also could see potential use as a coolant in the very high temperature reactor, a type of nuclear reactor.
==Coolant==
FLiNaK salt was researched heavily during the late 1950s by Oak Ridge National Laboratory as potential candidate for a coolant in the molten salt reactor because of its low melting point, its high heat capacity, and its chemical stability at high temperatures.〔http://www.energyfromthorium.com/pdf/FFR_chap12.pdf Lane, James A. "Chemical Aspects of Molten Fluoride Salt Reactor Fuels." Fluid Fuel Reactors. Reading, MA: Addison-Wesley Pub., 1958.〕 Ultimately, its sister salt, FLiBe, was chosen as the solvent salt for the molten salt reactor due to a more desirable nuclear cross section.〔http://www.energyfromthorium.com/pdf/FFR_chap12.pdf Lane, James A. Fluid Fuel Reactors. Reading, MA: Addison-Wesley Pub, 1958, p. 574〕 FLiNaK still gathers interest as an intermediate coolant for a high-temperature molten salt reactor where it could transfer heat without being in the presence of the fuel.〔Williams, D. F. (2006). (Assessment of candidate molten salt coolants for the NGNP/NHI Heat-Transfer Loop )〕
