THE Bi-BiBr$sub 3$ AND Bi-BiI$sub 3$ SYSTEMS
Technical Report
·
OSTI ID:4802604
The phase diagrams of the Bi-BiBr/sub 3/ and Bi-Bil/sub 3/ systems were determined. The experinmental techniques included sampling at temperature, visual observations, conventional thermal analyses, and differential thermal analyses. The consolute temperatures (538 deg at 62 mole% Bi and 458 deg at 78 mole % Bi for the BiBr/sub 3/ and BiI/sub 3/ systems, respectively) are considerably lower than that of the BiCl/sub 3/ system (780 deg at 51 mole % Bi). The freezing point depressions of the metal-rich and salt-rich regions were analyzed. The salts dissolved in molten bismuth were found to have a cryoscopic number of 3. As in the BiCl/sub 3/ case, this effect can be explained by dissociation of BiX/sub 3/ solute or by reaction of BiX/sub 3/ with Bi to form the monohalide. In the case of the salt-rich regions the data did not fit a curve corresponding to one single mechanism over the entire liquidus. (auth)
