Isothermal cross-section of the Yb-Pt-Ge phase diagram at 600°C

The isothermal section at 600 degrees C of the Yb-Pt-Ge phase diagram was investigated using metallography, X-ray powder diffraction and electron probe microanalysis. Only one binary compound, Yb3Ge5, was found in the Yb-Ge system. In the ternary Yb-Pt-Ge system the formation of the three phases, Yb2PtGe6, YbPtGe2, and YbPtGe was observed. The crystal structures of these compounds were determined. (C) 2000 Published by Elsevier Science S.A. All rights reserved.
