The present paper considers the physicochemical properties of valence electrons in the LiF–NaF–KF system within the framework of energy band theory. Here, the movement of the Fermi level in its band gap is equivalent to variations in the redox potential of the salt. When used to determine the limit level of the triple eutectic deoxidation, the electrochemical window identifi ed in the band gap may be suffi cient to suppress its corrosion activity in the liquid-salt reactor. However, this assumption, as well as the natural maintenance of this level in a mixture of three eutectic systems (LiF)0.99Li0.01, (NaF)0.97Na0.03, (KF)0.95K0.05, taken in the ratio of components (LiF)0.465(NaF)0.115(KF)0.42, requires experimental verification.
