Crystal-structure refinement of τ3-Cr4(Al, Si)11 by full-profile Rietveld analysis
Published online by Cambridge University Press: 01 March 2012
Abstract
Crystal structure of the triclinic ternary phase Cr4(Al, Si)11 was investigated by full-profile Rietveld analysis of powder diffraction data. Four hundred eighty-four reflections were refined to a final RBragg value of 5.00%. Cr4(Al, Si)11 is isostructural to Mn4Al11. Silicon atoms enter into the structure by partially replacing aluminium on the Al(1) and Al(2) sites.
