Crystal chemical investigation of the solid solutions of antimony and bismuth in palladium and platinum

Unit cell parameters were measured for the solid solutions Pd(Sb), Pd(Bi) and Pt(Sb) in the whole range of homogeneity. The composition dependence of the average atomic volume was investigated for the binary systems Pd–Sb and Pd–Bi. For the solid solutions Pd(Sb) and Pd(Bi), the partial atomic volum...

Description
Summary:Unit cell parameters were measured for the solid solutions Pd(Sb), Pd(Bi) and Pt(Sb) in the whole range of homogeneity. The composition dependence of the average atomic volume was investigated for the binary systems Pd–Sb and Pd–Bi. For the solid solutions Pd(Sb) and Pd(Bi), the partial atomic volumes of antimony and bismuth were determined. They are compared with the partial atomic volumes of the 4d (Ag⋯Te) and 5d (Au⋯Pb) elements measured in the palladium-based solid solutions. The increase in the partial atomic volume for the 4d elements Ag and Sb amounts to 16.3%, for the analogous heavy elements Au and Bi to 26.1%.
