â– Discover the history
Ancient Egypt, China and the Babylonians used the iron-bearing artifacts with high nickel content. The nickel produced by the Yunnanese people has a high nickel content, which is what Europeans call “Chinese Silverâ€. In 1751, the Swedish mineralogist AFCronsteclt used a separation method to produce nickel metal. Metal nickel is used in a large amount for social and economic development and has a history of more than one hundred years.
â– The nature of nickel
Nickel has good mechanical strength and ductility, is infusible and does not oxidize in air. The formation of a dense oxide film on the surface of the humid air at room temperature prevents the continued oxidation of the bulk metal. The etching of nickel by hydrochloric acid, sulfuric acid, organic acids and alkaline solutions is extremely slow. Nickel dissolves slowly in dilute nitric acid. Strong nitric acid makes nickel surface passivated and has corrosion resistance. Like platinum and palladium, nickel can absorb a large amount of hydrogen during passivation. The smaller the particle size, the greater the absorption. Important nickel salts are nickel sulfate and nickel chloride.
â– Nickel Resources
There are many types of nickel in the natural world. There are more than 10 major minerals with industrial value: nickel pyrite, sulfur-nickel-nickel (iron) ore, needle nickel ore, ferrous (iron) nickel ore, nickel-containing pyrrhotite, Sulfur nickel ore, red arsenite nickel ore, arsenite nickel ore, glistening arsenite nickel ore, dark nickel serpentine, nickel chlorite, kaolinite, green nickel ore, nickel magnetite, nickel matte, tourmaline, jade Nickel ore.
â– Preparation of nickel
The preparation of nickel mainly includes nickel sulfide nickel ore and nickel oxide nickel ore.
â– Use of nickel
Nickel is a very important non-ferrous metal raw material. The main purpose of nickel is to manufacture stainless steel, high-nickel alloy steel and alloy structural steel. It is widely used in aircraft, radar, missiles, tanks, warships, spacecrafts, nuclear reactors and other military manufacturing industries; in civil industry, nickel is often used. Made of structural steel, acid-resistant steel, heat-resistant steel, etc. used in a large number of machinery manufacturing, petroleum; nickel and chromium, copper, aluminum, cobalt and other elements can be composed of non-ferrous alloys. Nickel-based alloys, nickel-chromium-based alloys are high-temperature, oxidation-resistant materials used in the manufacture of jet turbines, resistors, electric heating elements, high temperature equipment structural parts, etc.; nickel can also be used as ceramic pigments and anti-corrosion coating; nickel-cobalt alloy is a permanent Magnetic materials are widely used in fields such as electronic remote control, atomic energy industry and ultrasonic technology. In the chemical industry, nickel is often used as a hydrogenation catalyst. In recent years, the use of nickel in color TVs, tape recorders and other communication equipment is also rapidly increasing.
