Research on the Detection of Gold Content in Yellow 18K Gold Jewelry
The gold content of yellow 18K gold jewelry was detected by X-ray fluorescence spectrometry,fire assay method,and scanning electron microscope(SEM).Research has shown that due to the influence of surface processing technology and material uniformity of yellow 18K gold,it is difficult to obtain accurate detection results by X-ray fluorescence spectroscopy.To obtain accurate gold content,the fire assay method is required for detection.
