“…FLiNaK salts are used in MSRs because of their high thermal conductivities, high specific heats, low viscosities, and high boiling points. However, FLiNaK molten salts can be corrosive to materials at high temperatures; corrosion resistance under high-temperature environments is compromised by the thermodynamic instability of the protective oxide layer [14][15][16]. Ceramics exhibit excellent properties, such as high melting point, hardness, strength, and chemical stability.…”
