The isothermal section of the Ni-Mn-Sb ternary system at 773K
The isothermal section of the Ni-Mn-Sb ternary system at 773K was investigated and constructed by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersion spectroscopy (EDS),and electron probe microanalysis (EPMA) techniques.The existence of 7 binary compounds NiMn, Mn2Sb,MnSb, NiSb2, NiSb, Ni5Sb2, Ni3Sb and 2 ternary compounds Ni2MnSb and NiMnSb was confirmed.The four binary compounds Ni3Sb (Cu3Ti-type structure, space group Prmmn), Ni5Sb2 (NisSb2-type structure,space group I2), NiSb2 (FeS2-type structure, space group Pnnm) and Mn2Sb (Cu2Sb-type structure, space group P4/nmm) in the sub-binary systems Ni-Sb and Mn-Sb are stoichiometric compounds, the homogeneity ranges of which are negligible.While the five single phase regions in the Ni-Mn binary system and the binary compounds MnSb and NiSb show a more or less homogeneity ranges formed by replacement of Mn and Sb for Ni.The Huesler compound μ (Ni2MnSb) has L21-type ordered structure with space group Fm-3m, a =0.6017 nm, and the crystal structure for the half-Huesler compound κ (NiMnSb) is Clb-type (F-43m) with a =0.5961 nm The homogeneity ranges of the two ternary compounds μ and κ at 773K were determined.
