 Title    Thermische Zersetzung und Lösungskalorimetrie von Ammoniumeuropiumchloriden Thermal Decomposition and Solution Calorimetry of Ammonium Europium Chlorides  
 Abstract    The thermal decomposition equilibria of ammonium europium chlorides (NH4)3EuCl6, (NH4)2EuC15 and NH4Eu2C17 have been investigated by total pressure measurements in a membrane zero manometer. The thermodynamic data of these solid phases have been deri­ ved from the decomposition functions. The standard enthalpies of solution in 4n HC1 (aq.) of (NH4)3EuC16, (NH4)2EuC15, NH4Eu2C17, EuC13 and Eu20 3 were measured. On the basis of these values and tabulated data, the standard enthalpies at 298 K of the ammonium europium chlorides were derived and compared with the obtained results from the total pressure measu­ rements. Data by total pressure measurement:
