NaF-KF-K2NbF7 fused salt temperature-solubility diagram.
J Am Ceram Society 1971 Jan; 54(1):11-12
Freezing and eutectic temperatures were determined for the NaF-KF-K2NbF7 ternary system and the NaF-K2NbF7, KFK2NbF7, and NaF-KF binary systems. The compound KF-K2NbF7 freezes congruently at 770 degrees C; eutectics occur at 708 degrees and 724 degrees C for high- and low-K2NbF7 mixtures, respectively. The NaF-K2NbF7 eutectic freezes at 658 degrees C. The ternary system has two eutectics, a high-KF mixture and a high-K2NbF7 mixture, which occur at 663 degrees and 652 degrees C, respectively.
