Abstract
In this study, the vaporization behaviour of solid Pd-rich phases in the
Pd-Pb, Pd-In and Pd-Sn systems was investigated by Knudsen-effusion-cell
coupled with mass-spectrometry. The Pb, Pd, In vapor pressures [no
Sn(g) has been detected in the vapor of Pd-Sn system] were evaluated in
the temperatures range 1190-1563 K from the ion intensities measured
over two-phases regions. Thermodynamic quantities were derived from
vapor pressure data. In particular, for the Pd-Sn binary, the
intermediate phase Pd7Sn2, the existence of which has been recently
proposed, has been studied here for the first time. Furthermore,
preliminary thermochemical data are presented for the diatomic
intermetallic molecules PdSn and PdPb, which have been for the first
time identified in the vapors in equilibrium over liquid solutions of
appropriate composition at higher temperatures (1935-2025 K). (C) 2000
