Sb-Bi Alloys and Ag-Cu-Pb-Sb-Bi Sulphosalts in the Jialong Cu-Sn Deposit in North Guangxi, South China
Although native bismuth is a relatively common mineral, native antimony is less abundant, and Sb-Bi alloys are relatively rare phases in Nature. Sb-Bi alloys and Ag-Cu-Pb-Sb-Bi sulphosalts have been discovered in the Jialong vein-type Cu-Sn deposit in North Guangxi, South China. The Jialong deposit is hosted by schist within the contact zone of a Neoproterozoic granite. Four stages of ore forma...
متن کاملX-Ray Photoelectron Spectroscopy Study of Passive Layers Formed on Pb-Sn and Pb-Sb Alloys
In this article, passivated Pb-Sn and Pb-Sb alloys with different compositions were studied by X-ray photoelectron spectroscopy (XPS). The passive films were found to have a double-layer structure. Both Sn and Sb were found to play an important role during the growth of passive film, which resulted in different compositions of passive filJ;l1s. The Pb oxides, Pb sulfate, SnlSb oxides, and Pb-Sn...
متن کاملDevelopment and Evolution of Nanostructure in Bulk Thermoelectric Pb-Te-Sb Alloys
Motivated by reports of exceptionally high zT > 2 in thin film superlattices or ‘‘quantum well’’ materials with nanometer sized features, we have undertaken a study of composite materials with nanoscale features that promise to provide similar structures in bulk material. Nanometer scale layers of PbTe and Sb2Te3 with periodicities of 180 nm to 950 nm form when quenched eutectic PbTe-Sb2Te3 mel...
متن کاملHigh-throughput ab initio analysis of the Bi–In, Bi–Mg, Bi–Sb, In–Mg, In–Sb, and Mg–Sb systems
Prediction and characterization of crystal structures of alloys are a key problem in materials research. Using high-throughput ab initio calculations we explore the low-temperature phase diagrams for the following systems: Bi–In, Bi–Mg, Bi–Sb, In–Mg, In–Sb, and Mg–Sb. For the experimentally observed phases in these systems we provide information about their stability at low temperatures. © 2005...
