The system Ce-Zn-B at 800 °C

► Isothermal section of system Ce-Zn-B at 800 °C. ► In System Ce-Zn, X-ray single crystal intensity data refinement of Ce3Zn11 and Ce3Zn22 and Rietveld refinement of Ce13Zn58. ► Two temperature modifications of Ce2Zn17, rhombohedral βCe2Zn17 (hT) and of hexagonal αCeZn7 (lT). ► No ternary compound in the System Ce-Zn-B (<50 at% Ce) at 800 °C.
