Abstract. We propose a model of phase transformation cubic argentite–monoclinic acanthite in silver sulfide Ag 2 S (AgS 0.5) as ordering in two argentite sublattices.We have determined the channel of the disorder–order transition including four nonequivalent superstructure vectors of stars {k 9} and {k 4}.For …
Acanthite Composition, Characteristics, Properties, Uses
Above 173 oC, Argentite is a form of Silver Sulfide. Below this temperature, Argentite changes to Acanthite. At room temperature, Ag2S actually stands for Acanthite. Acanthite Versus Galena. Acanthite and Galena are two most important ores of Silver. While Galena is a lead ore also containing silver (normally about 1 %); however, on processing ...

Facile synthesis, structure, and properties of Ag2S/Ag
Abstract Ag2S/Ag heteronanostructure has been produced by a simple one-stage chemical deposition from aqueous solutions of silver nitrate, sodium sulfide, and sodium citrate with the use of monochromatic light irradiation. For simultaneous synthesis of Ag2S and Ag nanoparticles, deposition has been performed from reaction mixtures with …
ARGENTITE
Argentite pertence ao grupo galena. O nome "argentite" às vezes também se refere a pseudomorfos de argentite: espécimes de acantina que ainda exibem alguns dos sinais externos da forma cristal cúbica, mesmo que sua estrutura cristalina real seja monoclínica devido à temperatura mais baixa.

Argentite
Argentite. Argentite, a silver sulfide mineral, is an important constituent of silver ore deposits. It contains 87% silver, and forms blackish-gray coatings or masses with a metallic luster and a shining black STREAK. Characteristic is the ease with which it is cut. Argentite is stable only above 179 deg C; thus, although few crystals found ...

The Mineral ACANTHITE/ARGENTITE
Argentite is a name applied to one polymorph (meaning many shapes) of Ag2S. Acanthite and argentite have the same chemistry., Ag2S, but different structures. Argentite has an isometric structure and is only stable at temperatures above. 173 degrees Celsius and if cooling from a melt, will form isometric crystals such.
Argentite: Mineral information, data and localities.
The name 'argentite' refers to the high-temperature form of silver sulphide, only stable over 177°C. Below this temperature, any samples of 'argentite' convert to acanthite. The name argentite is therefore used (confusingly) by some to describe pseudo-cubic pseudomorphs of silver sulphide (acanthite) where the original crystal form of the high-temperature cubic …

He speculated that argentite and a few other minerals of the galena group might be isometric only at high temperatures. Emmons, Stockwell & Jones 2 showed that this was the case and that the inversion temperature was about 180° C. That left only acanthite standing as a valid species at room temperature so now curators and collectors needed to ...

Significado de "argentite" no dicionário italiano
Argentite é um mineral de prata, com a fórmula Ag2S. O mineral puro é apenas estável a temperaturas acima de 177 ° C, sob o qual se torna acantyte, portanto, o que é comumente classificado como argentite, consiste estruturalmente em seu polimorfo monoclonal acinético. É por isso que o nome "argentite" foi desacreditado pela OMI.
