일반 설명

Ammonium thiosulfate is a non-toxic inorganic compound that is majorly used as a fertilizer and can be used as an alternative to cyanide based leaching. It has a hygroscopic nature and is soluble in water. It can be produced by the reaction of ammonia, water, and sulfur dioxide. It can be used as a photographic fixing salt.

애플리케이션

Ammonium thiosulfide can be used as a source of sulfur for the formation of cadmium sulfide thin films for electronic applications. It can also be used in the treatment of copper-gold ores for the recovery of gold.
