Description
Lead sulfide is found naturally occurring as metallic crystals called Galena. Galena is the primary source for metallic Lead. When crushed, lead sulfide is a black powder. Lead sulfide can also be made synthetically by reacting a soluble lead salt with Hydrogen sulfide or Sodium sulfide. Lead sulfide is used in ceramic glaze and as a source for the production of Lead sulfate. It is also used as a sensor in infrared detectors.
Synonyms and Related Terms
galena; plumbus sulfide; leaded bisilicate ash; lead sulphide (Br.); sulfure de plomb (Fr.)
