Acanthite - WikiMili, The Free Encyclopedia

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.

Silver: A native element, mineral, alloy, and byproduct

What is Silver? Silver is a soft, white metal that usually occurs in nature in one of four forms: 1) as a native element; 2) as a primary constituent in silver minerals; 3) as a natural alloy with other metals; and, 4) as a trace to minor constituent in the ores of other metals.Most of the silver produced today is a product of the fourth type of occurrence.

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 argentite has remained.
