ABSTRACT

Computer-aided Knudsen cell mass spectrometry is used for the thermodynamic investigations on ternary Au Co Pd melts over the entire range of composition. The digital intensity-ratio (DIR)-method has been applied for the determination of the thermodynamic excess quantities, and the ternary thermodynamically adapted power (TAP) series concept is used for algebraic representation of the thermodynamic mixing behavior. The corresponding TAP parameters aswell as the values of the molar excess Gibbs energies GE, of the molar heats of mixing HE, of the molar excess entropies SE, and of the thermodynamic activities at 1800K are presented.
