94. After condensation of oxidizer was complete, the solenoid stirrer was activated, liquid helium was supplied to the cooling bath, and the pressure in the heattransfer annulus adjusted to attain a cooling rate of about 1°K/minute. The emf of the thermocouple was continuously monitored, and the value recorded at 30 second intervals. The appearance of the oxidizer was observed visually during the experiment. The experiments were conducted with F2, with OF and with several mixtures of F2 and OF2. The recorded thermocouple potentiss were converted to temperatures from which cooling curve graphs (temperature vs. time) were plotted for each solution concentration. Figure 3 is a typical example. Temperatures at which breaks in the curves occurred were identified, and these were plotted on a temperature vs. concentration,graph to provide a typical phase diagram (Figure 4). The data used for plotting the phase diagram are tabulated in Table I. RESULTS AND DISCUSSION It was determined that; within the accuracy of the experiments, the binary system F OF exhibited typical eutectic formation with a probable break in the fluorine-rich$;qui$us curve due to a solid phase transition at 45 2 0. 5OK. The accuracy of the temperature measurements was t 0. 5OK. When the temperature-composition curves were plotted and extrapolated to their intersection (the eutectic), the error in composition was -f 2 mole %. This variation is indicated on the graphs by the bars through the experimental points. The errors in quantities of components used are believed to be considerably less than these. The eutectic temperature is estimated to be 43 ? 0. 5OK and.the eutectic composition 0. 59 -f 0. 02 mole fraction fluorine.
