A reddish shiny ductile metal. Face-centered cubic system. Relative density 8. 94; Melting point 1083 ℃, boiling point 2595 ℃. Soluble in nitric acid, hot concentrated sulfuric acid, very slowly soluble in hydrochloric acid, ammonia, dilute sulfuric acid, also soluble in acetic acid and other organic acids, insoluble in cold water and hot water. High-purity copper is a good thermoelectric conductor. Dark in the open air, the surface in the humid air gradually formed Green basic carbonate. Contact with acetylene forms an impact-sensitive compound. If the copper powder or dust copper is contacted with a strong oxidant, a vigorous reaction occurs.
with metal copper as raw material, dissolved in concentrated sulfuric acid, after electrolytic refining, high purity copper powder finished product.
high purity copper is an indispensable and valuable material in the atomic energy, rocket, missile, aviation, space navigation and metallurgical industry. High-purity copper is the best material for the neutron reflection layer of atomic reactor due to its strong heat absorption capacity, stable mechanical properties, high melting point and high temperature resistance. In the metallurgical industry is alloy steel additives, also used in refractory materials and special glass, integrated circuits, antennas and many other aspects.
It has a stimulating effect on the skin and respiratory tract. The dust irritates the eyes and causes corneal ulceration. Production personnel should be protected to avoid direct contact with dust and smoke. If contact is accidental, it should be washed with water immediately. Should be stored in a cool, ventilated, dry warehouse. Not with inorganic acids, strong alkali, edible raw materials and flammable materials are stored and mixed. Protection against rain and sun exposure during transport.
