| Calorimetrie an Ammoniumyttriumhalogeniden Calorimetry of Ammonium Yttrium Halides  | | | | Abstract
| The heat o f solution of all solid phases in the system YX3-NH4X with X = Cl, Br, I in 4 n HX was investigated. The enthalpies of formation of the ammonium yttrium halides are derived from the enthalpies of formation of Y X 3 and of NH4X and their heats of solution in An HX: Z\H^(NH4 Y 2Cl7,f,298) = — 561,5 ± 1,7 kcal/mol, Z\H^((NH4)3 YCl6,f,298) = -474,5 ± 1,3 kcal/mol, ziH ß((N H 4)3YBr6 f 298) = -400,8 ± 2,6 kcal/mol, _AH£((NH4)3 YI6,t-298) = -291,9 ± 3,0 kcal/mol. | | | |
