Silver sulfide is a kind of black powder belong to precious metals, the patent is: Ag2S, density in 685 ~ 7.23, melting point for 825 ℃; In the boiling point will decomposition, insoluble in water, but soluble in strong nitric acid and nitric acid, and soluble in Potassium cyanide and potassium chloride solution, in applications, Silver sulfide inlaid in dirty, often used in making ceramic art field also have applications. Silver sulfide of preparing by hydrogen sulphide ventilation with nitric acid silver instead.
Sulfur and silver mixed do not heat directly combined, silver oxide and sulfur heating generated vulcanization silver and sulphuric acid silver, moisture in the presence of sulfuric acid silver was sulfur into vulcanization silver, and glucosinolate and sodium and oxidize silver, nitric acid silver and other soluble silver reaction, and the produced glucosinolate and sulfuric acid silver unstable decomposition, or soluble sulfide with silver function, can be vulcanization silver of preparing way. Silver sulfide insoluble in ammonia, but soluble in alkali metal cyanide and nitric acid. Room temperature air it is stable, vacuum heating to 350 ° C, and the air when heated to decompose 1085 ° C below oxidation for sulfuric acid silver. Heat can be hydrogen reduction.
