Copper Cathode
Description of Copper Cathode
Copper is one of the basic chemical elements. In its nearly pure state, copper is a reddish-orange metal known for its high thermal and electrical conductivity. It is commonly used to produce a wide variety of products, including electrical wire, cooking pots and pans, pipes and tubes, automobile radiators, and many others. Copper is also used as a pigment and preservative for paper, paint, textiles, and wood. It is combined with zinc to produce brass and with tin to produce bronze.
The content of copper in the crust is about 0.01%, and in some copper deposits it can reach 3% – 5%. Copper in nature mainly exists in the form of compounds, namely copper minerals, which are mainly distributed in North America, Latin America and Central Africa. In terms of national distribution, the world’s copper resources are mainly concentrated in Chile, the United States, Zambia, the Commonwealth of Independent States and Peru.
The Definition of Copper Cathodes
The thick plate made of crude copper (including 99%) is used as anode, the thin plate made of pure copper is used as cathode, and the mixture of sulfuric acid and copper sulfate is used as electrolyte. After being electrified, copper dissolves into copper ions (Cu) from the anode and moves to the cathode, where electrons are obtained and pure copper is precipitated. Impurities such as iron and zinc, which are more active than copper, will dissolve into ions (Zn and Fe) with copper. Because these ions are not easy to precipitate compared with copper ions, they can be avoided to precipitate on the cathode as long as the potential difference is adjusted properly. Impurities such as gold and silver, which are less active than copper, are deposited at the bottom of the cell The copper plate produced in this way, called “Copper Cathode” or “Electrolytic Copper Cathode”, is of high quality and can be used to make electrical products.
Application of Copper Cathodes
Copper cathode is an non-ferrous metal which is closely related to human beings.Its widely used in electric, light industry, machinery manufacturing, construction, national defense industry and other fields.
Copper cathode is widely used in electronic industry, accounting for more than half of the total consumption. It is used for winding various cables, wires, motors, transformers, switches, printed circuit boards and other machinery and field.
