2016年10月24日 · A crystalline alloy of gold and bismuth, containing gold 68.22 per cent., bismuth 31.78 per cent., has been prepared by Pearce by means of liquation. By melting this with silver, a crystalline alloy corresponding to the formula AuAg was produced, and crystalline alloys of gold, silver and copper were also obtained.

低熔点亲铜元素 (LMCE)熔体超常富集贵金属的机制及其识别标志
2021年9月3日 · Combining research results of epithermal, orogenic, Carlin to Carlin-like and alkaline to meta-alkaline intrusion-related gold deposits, the authors discussed the formation and type of LMCE melts and their mechanisms for the enrichment of Au, Ag, PGE and other precious metals, and summarized mineral compositions and characteristic textures of mi...
Interfacial Reliability between Gold-Germanium solder and Au/Ni ...
In this paper, the reliability of solder joints is characterized by the interfacial reaction of gold-bismuth alloy solder joints and the change of microstructure with environment. The interface characteristics of AuGe alloy solder and eutectic sintering of Ni/Au pads with different gold thickness are studied.
