Description

Technical Field

[0001] The invention relates to the technical field of high-purity copper grains, in particular to a production process for changing the size of high-purity copper grains. Background Art

[0002] High-purity copper refers to high-purity copper, element symbol Cu, atomic number 29, atomic weight 63.55, peripheral electron configuration 3d104s1, located in the fourth period IB group. Atomic radius 127.8 picometers, Cu2+ radius 72 picometers, first ionization energy 750kJ / mol, electronegativity 1.9, common oxidation numbers +1, +2. Purple-red shiny metal, with good ductility and heat transfer and electrical conductivity. Density 8.96g / cm3, melting point 1083.4±0.2℃, boiling point 2567℃. The chemical properties are not very active. It is stable in dry air and easily generates basic copper carbonate, commonly known as copper green (Cu2(OH02CO3) in humid air containing carbon dioxide. When heated, it reacts with oxygen to generate copper oxide, reacts with halogens to generate copper halides, and reacts with sulfur to generate cuprous sulfide when heated. It does not react with water. It is insoluble in dilute hydrochloric acid and dilute sulfuric acid. It is soluble in nitric acid and hot concentrated sulfuric acid. It can also be dissolved in concentrated hydrochloric acid to generate H2CuCl3 and H2. It slowly dissolves in ammonia water. It is easily corroded by alkali. It is mainly used in the electrical industry, such as making wires, cables, and various electrical equipment. It is also used to make various alloys, such as brass, bronze, white copper, etc., and is also used for electroplating. Copper was discovered in ancient times. The main minerals are chalcopyrite (CuFeS2), chalcocite (Cu2S), cuprite (Cu2O), and malachite (Cu2(OH)2CO3). Copper ore is smelted to obtain crude copper, and finally electrolytically refined to obtain pure copper.
