The Density of Gold-Silver-Copper Alloys and its Calculation from the Chemical Composition
Gold-Silver-Copper Alloys Calculation
2009/7/29
On the assumption that the contribution of a component metal to the density of an alloy is linearly related to thedensity and concentration of this metal in the alloy it is possible to calculate the v...
The effects of platinum addition to gold and indium addition to a gold-platinum alloy on their optical propertieswere investigated using a computer-controlled spectrophotometer. Spectral reflectance d...
The surface tension and the density of some gold alloys have been measured and their wetting behaviourinvestigated in relation to different ceramic supports. Relationships between surface tension and ...
Non Destructive Analysis of Gold Alloys Using Energy Dispersive X-Ray Fluorescence Analysis
Gold Alloys Energy
2009/7/29
Gold alloys can be analyzed quickly and in a nondestructive
manner using energy dispersive x-ray
fluorescence analysis (ED-XRFA). Two factors determine
the accuracy of the measurement; the repeatab...
