Abstract: Application of the Le Chatelier-Shreder equation to the anal. of coordinates of the eutectic point on the liquidus curve of Li, Na, and K hexafluoroaluminate in the subsystems M3AlF3-AlF3 was used to prove the presence of compds. LiAlF4, NaAlF4, and KAlF4, resp., in these systems. Further, the existence of a chem. compd. in the system KF-AlF3 in the compn. range 75-55 mol% KF is predicted. On the other hand, the possibility of the existence of compds. of the type Li5Al3F14 or Li3Al2F9 in the system LiF-AlF3 was disproved.
