Freezing and eutectic temperatures were determined for the NaF‐KF‐K 2 NbF 7 ternary system and the NaF‐K 2 NbF 7 , KFK 2 NbF 7 , and NaF‐KF binary systems. The compound KF‐K 2 NbF 7 freezes congruently at 770°C; eutectics occur at 708° and 724°C for high‐ and low‐K 2 NbF 7 mixtures, respectively. The NaF‐K 2 NbF 7 eutectic freezes at 658°C. The ternary system has two eutectics, a high‐KF mixture and a high‐K 2 NbF 7 mixture, which occur at 663° and 652°C, respectively.
