Abstract: The phase diagrams of the binary system KF–AlF₃ as well as a part of the ternary system KF–AlF₃–Al₂O₃ in the range up to 10 mole % Al₂O₃ at the mole ratios n(KF)/n(AlF₃) = 2.35, 2.2, and 1.85 were measured using the thermal analysis method.
In the system KF–AlF₃ the coordinates of the eutectic points are: E1: 8 mole % AlF₃, 821.2ºC; E₂: 45 mole % AlF₃, 559.0ºC.
In the ternary system the crystallization area of kraft was investigated.
