• Atmospheric corrosion products of copper were identified by scanning electron microscopy, X-ray microanalyzer, X-ray diffraction, and electron diffraction. The samples were exposed to the air for periods of 1/2, 1, 3, and 6 months. The results obtained were as follows: (1) The corrosion products were composed of chlorides, sulfur compounds, and oxides. Among them, the constituents identified were Cu2O, CuCl, 3Cu(OH)2⋅CuCl2, and Cu2S. (2) In conclusion, it is very defective to make analysis of the corrosion products only by X-ray diffraction and electron diffraction with simple results of measurements. Therefore, the analysis must be made with comprehensive knowledge by using other various techniques as possible.
