Polymorphism in the Sr-Bi System
Journal of Phase Equilibria and Diffusion, 2021Eleven examples of hexagonal and orthorhombic polymorphs of intermetallic compounds having 5:3 stoichiometry are listed in the International Crystal Structure Database. A transition temperature between them has only been determined for the Yb–Sb and Sr–Bi systems, but results on the Sr–Bi system are discrepant with those on the Yb–Sb system, in which ...

Calorimetric investigation of Pb–Bi system
Journal of Alloys and Compounds, 2010Abstract The enthalpy of formation of ɛ-compound, Pb0.68Bi0.32, was determined at 448 K by successive precipitation method. The enthalpy of formation of ɛ-compound, Pb0.71Bi0.29, was determined by tin and lead solution calorimetry. By successive precipitation method, the Δ H f ° of Pb0.68Bi0.32 from Pb(l) and Bi(l), at 448 K, was −3.85

Thermodynamic reassessment of the Au–Bi system
Calphad, 2006Abstract The Au–Bi system has been thermodynamically reassessed through the Calphad approach by combining new experimental data, in particular the enthalpies of mixing of the liquid phase recently available in the literature. A good agreement is obtained between the calculated and experimental invariant equilibria.

Assessment of the mg-bi system
Calphad, 1992Abstract The thermodynamic data for the Mg-Bi system have been optimized from measured thermodynamic data. A two-sublattice model for ionic melt was used to express the Gibbs free energy of the liquid phase. The high and low temperature non-stoichiometric Mg3Bi2 compounds were described by a two-sublattice model, Mg3(Va, Bi)2.

The Generalized Bi-System Multiplier
Canadian Journal of Economics and Political Science, 1949Within recent years significant additions have been made to the theory of the multiplier in its application to the study of income movements among economic systems. It is the object of this paper to introduce a graphical method into the analysis of the bi-system multiplier, to develop a generalized formulation of the bi-system multiplier of which the ...

Electromagnetic Properties of Bi System Superconductor
Materials Science Forum, 2007Effects of Ag2O doping on the electromagnetic properties in the BiSrCaCuO superconductors. The electromagnetic properties of Ag2O doped and undoped BiSrCaCuO superconductor were evaluated to investigate the contribution of the pinning centers to the magnetic effect. It was confirmed experimentally that a large amount of magnetic flux was trapped in the

57Fe Mössbauer Spectroscopy for Bi-System Superconductors
1995Mossbauer effect of 57Fe in a sample of Bi1.8Pb0.4Sr2.0Ca2.2(Cu0.9757Fe0.03)3.2O z [Bi-(2223)] has been measured from 4.2K to room temperature to study magnetic and phonon structures of Cu-O layers. A widely split spectrum is obtained at 4.2K, which indicates the existence of hyperfine magnetic interaction of 57Fe probe in Cu sites.
