“…Bromide systems.--Experiments in this system were conducted in the NaBr-KBr eutectic mp 644~ (19) to which about 5 w/o (weight per cent) ZrBr4 was added. The phase diagram of NaBr-KBr-ZrBr4 is unknown, but by analogy with the NaC1-KCI-ZrC14 diagram a low melting eutectic rich in ZrBr4 might be expected around 70-80% ZrBr4 and 200~176 Accordingly the temperature was held at 250~ for several hours and then slowly raised to the operating temperature.…”

Exploratory experiments in chloride, bromide, and mixed chloride‐fluoride melts always produced dendritic zirconium deposits. Pure fluoride systems consisting of ZrF4 dissolved in alkali fluoride solvents produced coherent deposits of metal, some as thick as 0.1 in. with no indication of reaching a thickness limit, on electrolysis at 750 °C and 30 ma/cm2 cathode current density. Analysis and material balance experiments showed that reduced compounds were absent in these fluoride systems. Chronopotentiometric measurements indicate that the zirconium is deposited from the tetravalent state in a single four‐electron step which would appear to be irreversible. The addition of KBF4 , K2TiF6 , and Al2O3 to a working zirconium bath results in the deposition in coherent form of the compound ZrB2 and the alloys normalZr‐normalTi and normalZr‐normalAl . The ZrB2 plate was 11 mils thick and showed no evidence of reaching an upper limit of thickness, while both alloys were smooth and fine‐grained in nature, the normalZr‐normalAl deposit showing a particularly interesting rhythmic banded structure.

Intermolecular Forces in the NaF + KF + K₂NbF₇ System: Investigation of Surface Tension and Viscosity

The surface tension and viscosity of the NaF (1) + KF (2) binary system and of the NaF (1) + KF (2) + K2NbF7 (3) ternary system have been measured over the whole concentration range under an inert atmosphere. A modified Redlich–Kister type equation has been used for the description of the viscosity dependence on the composition. The surface tension of the NaF (1) + KF (2) + K2NbF7 (3) system changes continually and decreases from K2NbF7 through KF to NaF. The viscosity of the NaF (1) + KF (2) + K2NbF7 (3) system decreases from K2NbF7 through NaF to KF. In the case of excess surface tension, the system behavior is ideally close to the KF-rich side, and for excess viscosity, the behavior is ideally close to the NaF-rich side.
