New Ternary Compounds Yb2Pt3Si2 and Yb3Pt5Si: Crystal Structures and Phase Equilibria
Source abstract
Abstract
Abstract— Two new ternary intermetallic compounds, Yb2Pt3Si2 and Yb3Pt5Si, have been identified in the Yb–Pt–Si system in the composition region from 0 to 42 at % silicon and from 20 to 43 at % ytterbium. Using Rietveld refinement of X-ray powder diffraction data, we have determined crystallographic parameters of the new compounds. Yb2Pt3Si2 has an orthorhombic structure (Sc2Pt3Si2 structure type, sp. gr. Pbam). The Yb3Pt5Si compound crystallizes in a body-centered orthorhombic structure (Ce3Pd5Si structure type, sp. gr. Imma). Phase equilibria in the 850°C isothermal section of the Yb–Pt–Si system have been studied in the above composition region.
