Argentite sample The unit cell of argentite. In mineralogy, argentite (from Latin argentum ' silver') is cubic silver sulfide (Ag 2 S), which can only exist at temperatures above 173 °C (343 °F), [1] 177 °C (351 °F), [2] or 179 °C (354 °F). [3] When it cools to ordinary temperatures it turns into its monoclinic polymorph, acanthite.

Argentite, silver sulfide of the orthorhombic system, one of the oldest silver ore minerals. In addition, there are several more mixed minerals, part of the name of which is also silver glance: Antimony-silver glance (German: Antimonsilberglanz) — Stephanite; Black silver glance (German: Schwarzsilberglanz) — Stephanite
An example of a readable book [b]. Each of the nine countries covered by the library, as well as Reporters without Borders, has an individual wing, containing a number of articles, [1] available in English and the original language the article was written in. [2] The texts within the library are contained in in-game book items, which can be opened and placed on stands to be read by multiple ...
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver. [5]Galena is one of the most abundant and widely distributed sulfide minerals.
Silver is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver is a naturally occurring element.
Acanthite var. argentite (a pseudomorph after argentite) and β-quartz pseudomorphs are sometimes sold. [31] Ramdohr (1936) discovered that the type material of schapbachite (Ag 0.4 Pb 0.2 Bi 0.4 S) was a mixture of galena (PbS) and matildite (AgBiS 2). [32] It was discredited (1982) as it was found unstable at 'standard temperature and ...
Stibnite Realgar. The sulphide minerals are a class of minerals containing sulphide (S 2−) or disulphide (S 2− 2) as the major anion.Some sulfide minerals are economically important as metal ores.
