“…Miyazawa and Ariga (2001) presented their results on characterization of Ag-Bi-Zn alloys, while most complete data on that system was given by Ohtani et al (2004). There are also references concerning constitutive binary subsystems (Gandova and Vassilev, 2013;Premović et al, 2013;JendrzejczykHandzlik et al, 2007).…”

Structural, mechanical and electrical properties of selected alloys in ternary Ag-Bi-Zn system are presented in this paper. Chosen alloys were investigated using X-Ray Diffraction (XRD), light optical microscopy, Scanning Electron Microscopy combined with Energy Dispersive Spectrometry (SEM-EDS), as well as by electrical conductivity and Brinell hardness measurements. Isolines of electrical conductivity and hardness for the entire Ag-Bi-Zn system were calculated using regression models. RESUMEN: Propiedades estructurales, mecánicas y eléctricas de aleaciones del sistema ternario Ag-Bi-Zn.Este trabajo estudia las propiedades estructurales, mecánicas y eléctricas de aleaciones seleccionadas del sistema ternario Ag-Bi-Zn. Las aleaciones elegidas se han caracterizado por medio de difracción de rayos X, microscopía óptica, microscopía electrónica de barrido combinada con espectrometría de dispersión de energía, así como por medio de medidas de conductividad eléctrica y dureza Brinell. Por medio de modelos de regresión se han calculado las líneas de isoconductividad eléctrica y dureza para todo el sistema Ag-Bi-Zn.

Noble metals Pt, Au, and Ag as nucleating agents in BaO/SrO/ZnO/SiO2 glasses: formation of alloys and core–shell structures

et al. 2022

Noble metals such as Ag can be used as nucleation agents in glass ceramics. In glasses, it is incorporated predominantly as AgI. At temperatures slightly above the glass transition temperature, Tg, AgI reacts with SbIII to SbV and metallic Ag. Usually, face-centered cubic Ag particles are nearly spherical and get facetted during crystal growth. By contrast, in the case of BaO/SrO/ZnO/SiO2 glasses, silver has, in comparison to other noble metals, another significant, yet different effect. It forms metallic particles (hexagonal phase) with plate-like morphology during thermal treatment at 675 °C. In the second step of thermal treatment at 760 °C, this phase most probably expels some metallic Sb, which is oxidized by SbV (present in the surrounding glass phase) to SbIII. As a result, the plate-like morphology is maintained and a crystalline shell around the metallic core is formed, mainly consisting of ZnO with some SiO2 and antimony oxide, as proved by scanning transmission electron microscopy combined with energy-dispersive X-ray spectroscopy. This shell triggers the volume crystallization of Ba0.5Sr0.5Zn2Si2O7, a phase with low thermal expansion. By comparison, alloying of Au with Sb does not occur according to the phase diagram. Instead, a thermal treatment at temperatures slightly above Tg leads to nanocrystalline, spherical Au particles. Hence, alloying and subsequent decomposition of the alloy is a prerequisite for the formation of plate-like noble metal particles.
