Application

Purple copper bar the use of the more expansive than pure iron, each year, 50% of the copper electrorefining is pure copper, used in the electrical industry. Here copper, really have to be very pure, copper above 99.95%, very small amounts of impurities, especially phosphorus, arsenic, aluminum, etc., can greatly reduce the conductivity of the copper. Oxygen in copper (copper easily when mixed with a small amount of oxygen) had a great influence on conductivity, used for electrical industry generally must be oxygen-free copper brass. In addition, the impurities such as lead, antimony and bismuth can make the crystallization of copper can not be together, cause heat brittle, also can affect the pure copper processing. The purity of high pure copper, typically by electrolysis refining: put not pure copper anode (i.e., crude copper), pure copper cathode, copper sulfate solution as electrolyte. When an electric current passes through the anode impure copper melting gradually, pure copper precipitation will gradually on the cathode. Such a refined and copper; Purity can reach 99.99%
