Lead (II) Sulfide (PbS) Semiconductors

Lead sulfide is an inorganic compound with the chemical formula PbS. It is also known as galena, which is the principal ore and important compound of lead. It is one of the earliest materials to be used as a semiconductor as it tends to crystallize in sodium chloride. Lead sulfide is toxic if it is heated to decomposition, which forms lead and sulfur oxides.

Galena Lead Sulfide

Galena Lead Sulfide. Galena Wikipedia. Galena is the main ore of lead, used since ancient times. Because of its somewhat low melting point, it was easy to liberate by smelting. It typically forms in lowtemperature sedimentary deposits. In some deposits the galena contains about 1–2% silver, a byproduct that far outweighs the main lead ore in revenue. In these deposits significant amounts of ...

The main lead ore, galena is essentially lead sulfide. Galena is easy to spot since it usually displays a silvery gray color and if broken will show perfect cleavage in three directions. Galena will oxidize or "tarnish" to a dull grey when exposed to the elements. It has a specific gravity of around, which makes it fairly heavy and dense. In crystalline form galena exhibits cubic ...
