[Identification of realgar and arsenopyrite and their sublimates]

In this paper, two traditional Chinese medicinal minerals realgar and arsenopyrite, as well as their sublimates are identified in their nature, physical and optical properties, chemical compositions and trace elements. The result has shown that there are marked differences among realgar, arsenopyrite and their sublimates, and it should be particularly noted that the difference between the two sublimates will certainly affect the quality of the two minerals that are used as poisonous drug in China.
