Abstract: Introducing B₂O₃ into molten LiF, lithium metaborate and volatile BF₃, which escapes from the melt, are formed. This leads to the volume contraction. In the system KF-B₂O₃ the addition of B₂O₃ into molten KF leads to the formation of more polymerized potassium tetraborate and KBF₄, which causes the volume expansion. The dependence of the molar volume on composition in the ternary system LiF-KF-B₂O₃ and the quaternary system LiF-KF-B₂O₃-TiO₂ was described.
