| has gloss | eng: Silver sulfide (or Silver sulphide in British English), Ag2S, is a black sulfide of silver. It is black and constitutes the tarnish that forms on silver when exposed to the hydrogen sulfide of the atmosphere. It is found in nature as relatively low temperature mineral acanthite. The name argentite refers to a cubic form, which, due to instability in "normal" temperatures, is found in form of the pseudomorphosis of acanthite after argentite. When formed on electrical contacts operating in an atmosphere rich in hydrogen sulfide, long filaments known as Silver Whiskers can form. Acanthite is an important ore of silver. Structure There are three forms, monoclinic acanthite, stable below 500°C, body centered cubic so-called argentite, stable above 176°C, and a high temperature face-centred cubic form stable above 586°C. The higher temperature forms are electrical conductors. The boiling temperature is zero. |
