• Acanthite - Wikipedia

    en.wikipedia.org/wiki/Acanthite Acanthite is a form of silver sulfide with the chemical formula Ag 2 S. It crystallizes in the monoclinic system and is the stable form of silver sulfide below 173 °C (343 °F). Argentite is the stable form above that temperature. As argentite cools below that temperature its cubic form is distorted to the monoclinic form of acanthite.

    www.mindat.org/min-10.html Acanthite is the low-temperature modification of silver sulphide. All natural silver sulphide specimens at room temperature are acanthite. The structure of Argentite, the high-temperature cubic (isometric) form cannot be quenched.At atmospheric pressure, pure argentite is stable above 177°C and acanthite is stable below 177°C.

Acanthite and Argentite are usually grouped together in mineral guides as one mineral. However, they are scientifically recognized as two unique minerals, even though they are composed of the same substance.
  • Acanthite | mineral | Britannica

    www.britannica.com/science/acanthite Argentite is the high-temperature form of acanthite. Like several other sulfides, selenides, and tellurides of silver and copper, argentite forms isometric crystals at high temperatures.Upon cooling these crystals invert from isometric (cubic) to monoclinic structures while remaining unchanged in external appearance.
  • ACANTHITE/ARGENTITE (Silver Sulfide)

    www.galleries.com/Acanthite Acanthite is sectile which means that it can be cut into by a knife just like lead. Acanthite is generally a very valuable mineral specimen, due mostly to the high silver content and the rarity of good crystals. It is a pleasure to own fine acanthite specimens once they are finally procured.

  • Argentite - Wikipedia

    en.wikipedia.org/wiki/Argentite In mineralogy, argentite (from the Latin argentum, silver) is cubic silver sulfide (Ag 2 S), which can only exist at temperatures above 173 °C, 177 °C or 179 °C. When it cools to ordinary temperatures it turns into its monoclinic polymorph, acanthite. Argentite belongs to the galena group.
