Cadmium (Cd; at. wt. 111.7), a white, soft crystalline metal, sp. gr. 8.6, which is frequently found associated with zinc in the ores of this metal. It melts at 315 C, and, being more volatile than zinc, is found in the portions of the metal which distil over first when the ores are heated with charcoal. It dissolves slowly in dilute acids and forms salts, as Cadmium Chloride, etc. The sulphide CdS is an insoluble yellow powder, occurring native as Greenockite, and is employed as a pigment.
