Abstract
The high content gold on the market is mainly divided into ordinary gold, "3D" hard gold, "5G" gold and ancient gold. In order to explore the physical and chemical properties of four types of high content gold, a number of properties and composition studies were carried out in this paper. The physical properties of four types of high content gold were investigated by transmission electron microscopy, digital microscopic Vickers hardness tester and surface roughness tester. The chemical properties was investigated by nitrogen oxygen hydrogen analyzer, carbon sulfur analyzer and inductively coupled plasma mass spectrometer. Finally, the performance and composition evaluation results of four types of high content gold on the market were obtained.
