Description
Several forms of copper chloride are found as minerals: including Atacamite, Paratacamite, eriochalcite, tolbachite, and nantokite. Pure anhydrous copper chloride is composed of dark yellow crystals that absorb water to form green deliquescent crystals. Copper chloride is used as a Disinfectant, Fungicide, and Wood preservative. It is also used as a fixer in photography, a Mordant in dyeing textiles and a component in indelible inks. In metallurgy, copper chloride is used refine Gold and Silver, to recover Mercury from ore, and to electroplate Copper on Aluminum. Copper chloride is also used as a Glass and ceramics pigment.
Synonyms and Related Terms
