A solid solution modeling approach somehow analogous to the EoS approach for fluids: Application to equilibria involving fluid phases and solid solutions
(Elsevier Science, 2021-11)
In the present work, a modeling approach applicable over wide ranges of temperature and pressure to the representation of the thermodynamic properties of pure components in solid state is extended to the case of solid ...
The solid solution between platinum and palladium in nature
(2013-07-15)
Chemical and structural data are reported for platinum-palladium intermediates from two nuggets found at Corrego Bom Sucesso, Minas Gerais, Brazil. Three grains with simple stoichiometries (i.e. PtxPd1 -x with x ∼0.67, ...

Morphotropic phase boundary and electrical properties of 1-x[Bi 0.5Na0.5]TiO3 -xBa[Zr0.25Ti 0.75]O3 lead-free piezoelectric ceramics
(2013-07-01)
Lead-free solid solutions (1-x)Bi0.5Na0.5TiO 3 (BNT)-xBaZr0.25Ti0.75O3 (BZT) (x=0, 0.01, 0.03, 0.05, and 0.07) were prepared by the solid state reaction method. X-ray diffraction (XRD) and Rietveld refinement analyses of ...

Formation of nano-crystalline structure at the interface in Cu–C composite
(Elsevier, 1999)
Formation of Cu–C composite is a difficult technological problem: carbon is practically insoluble in copper. We show that the heat treatment of the Cu–C composite leads to the formation of a thin (approximately 50 nm) ...
Relationship between the chemical composition and atomic volume in ag- x % at zn (x ≤ 20) solid solutions
(Universidad Nacional de Colombia Sede Medellín, 2014-04-24)
In this work the relationship between the chemical composition and atomic volume in the Ag – x % Zn (x ≤ 20) system was studied. For this purpose, 10 solid solutions were obtained by means of casting and mechanical alloying. ...
