In mineralogy, argentite is cubic silver sulfide, 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. The International Mineralogical Association has decided to reject argentite as a proper mineral.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.

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. For detailed physical…Argentite | mineral | BritannicaArgentite is a fairly rare silver ore from hydrothermal lead-zinc-silver and gold veins, mainly occurring in their cementation zone. It is associated with pyrite, sphalerite, galena, its dimorph acanthite, and many other silver minerals (polybasite, pyrargyrite, tetrahedrite ); it is also a mineral accompanying gold in the epithermal veins ...Argentite - Encyclopediaاحصل على السعر
Argentite is stable above 179 C. Acanthite is stable below 179 C. Name Pronunciation: Argentite + Pronunciation : Synonym: ICSD 9586 : PDF 4-774 : Silver Glance : Argentite Image: Images: Argentite Acanthite. Comments: Dark metallic acanthite crystals up to 3 mm. Most of the crystals are a cubic habit, so the acanthite is pseudomorphing the ...Characteristic is the ease with which it is cut. Argentite is stable only above 179 deg C; thus, although few crystals found appear outwardly to be isometric, they are actually composed of acanthite, a chemically identical paramorph belonging to the monoclinic system. Argentite's hardness is 2 - 2.5 and specific gravity is 7.2-7.4.Argentite - Rausser College of Natural ResourcesIn general, in situ X-ray analysis of silver sulfide revealed only acanthite at T ≤ 433 K and only argentite at T > 453 K. This fact and the data of [28, 30–32, 34, 35] suggest that the heating of monoclinic α-Ag 2 S acanthite to a temperature of about 449–450 K leads to a polymorphic phase transition with the formation of bcc β-Ag 2 S argentite. ...Atomic Displacements in the α–β Phase Transition in Agاحصل على السعر
