The Bureau of Mines is developing melting data for binary combinations of the alkaline earth fluorides and yttria to facilitate the formulation of slag composition. Liquidus and solidus temperatures and solid solubilities were determined for the baf2-y2o3 system, and the information is presented as the phase diagram. The phase diagram was constructed from data obtained by ceramography, x-ray diffraction, and thermal analysis of specimens encapsulated in small molybdenum ampoules. The data indicate a simple eutectic system with maximum terminal solid solubilities of less than 1 mole percent. The eutectic temperature is 1,343 deg. C, and the composition of the eutectic is less than 1 mole percent y2o3.
