THERMOCHEMISTRY OF SAMARIUM
Technical Report

OSTI ID:4190186
Heats of solution of samarium (III) oxide and chloride in hydrochloric acid and of samarium (III) oxide, sulfate, and hydrated sulfate in sulfuric acid were measured. The heats of solution of this hygroscopic oxide are larger than those from the literature, probably because of more complete removal of water in the present study. From the literature value for the heat of combustion of samarium, the heats of formation of samarium (III) chloride and sulfate are - 244.18 plus or minus 0.41 and -928.5 plus or minus 1.6 kcal/mole, respectively. The heat of hydration of the sulfate is --34.7 plus or minus 1.0 kcal/ mole. The heats of formation of other samarium compounds have been recalculated, using the new data. (auth)
