Abstract
The alkaline-earth fluoride system baf2-srf2 was studied because the liquidus temperatures were thought to be sufficiently high to make compositions in this system useful as slags for electroslag melting of reactive metals such as ti and zr. Melting point temperatures were determined for baf2 and srf2. The melting point of srf2 is approximately 200 deg c below that of ti and 50 deg c above that of caf2, which is the most commonly used slag for melting reactive metals. The high-temperature densities for all mixtures in the baf2- srf2 system are greater than that for caf2, but less than that for molten ti above its melting point. The heats of fusion for the pure components (3.0 and 4.26 Kcal mole-1 for baf2 and srf2, respectively) are less than those for caf2 (6.78 Kcal mole-1).
