Galena is a lead sulfide mineral with a chemical composition of PbS. It is the world's primary ore of lead and is mined from a large number of deposits in many countries. It is found in igneous and metamorphic rocks in medium- to low-temperature hydrothermal veins.

Galena (lead sulfide) is easily the most important source of lead, and often contains enough silver impurities that it is also a valuable source of that metal.

Lead sulfide is a sulfide of lead that occurs naturally as the mineral galena. It is used as a semiconductor and infrared detector. Lead is a heavy metal and stable element with the symbol Pb and the atomic number 82, existing in metallic, organic, and inorganic forms.

2023年9月4日 · Galena, a mineral of both historical and geological significance, is a lead sulfide mineral with the chemical formula PbS. It stands out with its distinctive metallic luster and cubic crystal structure, often appearing as shiny, cubic or octahedral crystals.

Lead (II) sulfide (also spelled sulphide) is an inorganic compound with the formula Pb S. Galena is the principal ore and the most important compound of lead. It is a semiconducting material with niche uses.

2019年4月1日 · Galena, historically also named lead glance, is among the most abundant sulfides. Besides forming aesthetic mineral specimens, galena is the primary lead ore. And galena itself was a first semiconductor ever used. The chemical formula of galena is PbS (lead sulfide).

2021年12月12日 · Lead (II) sulfide is an inorganic compound with the formula PbS. Lead (II) sulfide can be roasted in air at high temperatures to form lead (II) oxide and sulfur dioxide. Lead oxide can be further reduced with carbon to lead metal. Lead (II) sulfide is …

Lead (II) sulfide, also known as plumbuus sulfide, is a chemical compound. Its chemical formula is PbS. It contains lead and sulfide ions. The lead is in its +2 oxidation state. Lead (II) sulfide is a black solid. It does not react with acids. It reacts with …

galena, a gray lead sulfide (PbS), the chief ore mineral of lead. One of the most widely distributed sulfide minerals, it occurs in many different types of deposits, often in metalliferous veins, as at Broken Hill, Australia; Coeur d’Alene, Idaho, U.S.; Clausthal Zellerfeld, Ger.; and Cornwall, Eng. Large deposits also occur as replacements ...
