Introduction to the uses and application fields of nickel
Nickel has good plasticity, corrosion resistance and magnetic properties, so it is mainly used in fields such as steel, nickel-based alloys, electroplating and batteries. It is widely used in various military manufacturing industries such as aircraft and radar, civil machinery manufacturing and Electroplating industry, etc.
Steel field
Because nickel has good corrosion resistance, high temperature resistance, rust resistance and other properties, it is widely used in steel fields such as stainless steel and alloy steel.
Stainless steel
Nickel consumption is the largest in stainless steel applications, and 2/3 of the world's primary nickel ores are used in the production of stainless steel. Nickel-containing stainless steel can not only resist the corrosion of atmosphere, steam and water, but also resist the corrosion of acid, alkali and salt. Therefore, it is widely used in chemical industry, metallurgy, construction and other industries, such as manufacturing petrochemical industry, textile, light industry and nuclear energy. Containers, towers, tanks, pipes, etc. that require welding in other industries; manufacturing corrosion-resistant high-pressure equipment such as synthesis towers, washing towers, condensation towers, and stripping towers in urea production. According to the different proportions of nickel, nickel-containing stainless steel is mainly divided into: austenitic stainless steel, austenite-ferrite duplex stainless steel, and precipitation hardening stainless steel.
alloy steel
Alloy steel is also called special steel. Because of its different element composition ratios and different types, the participation of nickel can improve the strength of the alloy and maintain its good plasticity and toughness. Nickel-containing alloy steel is mainly used in the manufacture of acid-resistant towers, medical equipment, and daily necessities in chemical production, as well as in machinery manufacturing, transportation, and military industries such as bridge renovation and warship construction.
Nickel-based alloy field
Nickel-based alloy refers to a type of alloy that has comprehensive properties such as high strength and certain resistance to oxidation and corrosion at high temperatures of 650 to 1000°C. According to the main properties, it can be subdivided into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys and nickel-based shape memory alloys, etc. Nickel-based alloy products mainly include: electric stoves, electric irons, turbine engine turbine disks, combustion chambers, turbine blades, color televisions, communication equipment, clocks and pendulums in measuring tapes, manufacturing furniture, precision tools with permanent magnet properties, Automatic opening structural parts used on spacecraft, self-exciting fasteners used in the aerospace industry, and artificial heart motors used in biomedicine, etc. It is widely used in industrial fields such as aviation, shipbuilding, chemical industry, electronics, medicine and energy.
Electroplating field
Nickel plating refers to covering steel and other metal substrates with a durable, corrosion-resistant coating. Its corrosion resistance is 20% to 25% higher than that of zinc plating. Nickel-plated items are beautiful, clean, and not easy to rust. The processing volume of electroplating nickel ranks second after zinc electroplating, and its consumption accounts for about 10% of the total nickel production. Nickel plating is divided into electroless nickel plating and chemical nickel plating. The characteristics of electroless nickel plating and electroless nickel plating are analyzed as follows:
Battery field
Metal-plated nickel is also used in the battery field, mainly including nickel-hydrogen batteries, cadmium-nickel batteries and nickel-manganese batteries. The most rapid development in recent years is the increasingly practical MHx-Ni battery. Its advantages are non-toxic, green and pollution-free. The battery reserve is 30% more than that of nickel-cadmium batteries. It is lighter than nickel-cadmium batteries and has a longer service life. The disadvantages are The price is more expensive than nickel-cadmium batteries, and the performance is worse than lithium batteries. It is mainly used in mobile communications, notebooks, video recorders and other fields. It is also used in military industry, national defense, high-tech and other fields. Cars powered by such batteries are already on the market.
Nickel physical and chemical properties
Nickel physical properties
Nickel is a silver-white metal with good mechanical strength and ductility. It is insoluble in water and has strong corrosion resistance to acids and alkalis, but is easily soluble in dilute nitric acid and aqua regia. Not easily oxidized in air. High temperature resistance, melting point 1452℃, boiling point 2900℃. Density is 8.902g/cm³.
Chemical Properties of Nickel
At normal temperature, nickel forms a dense oxide film on its surface in humid air and turns black, which can prevent the metal from continuing to oxidize. Organic acids, hydrochloric acid, sulfuric acid and alkaline solutions etch nickel very slowly. Nickel dissolves slowly in dilute nitric acid. Fuming nitric acid can passivate the nickel surface and make it corrosion resistant. Nickel, like platinum and palladium, can absorb a large amount of hydrogen during passivation. The smaller the particle size, the greater the absorption amount. The important salts of nickel are nickel sulfate and nickel chloride. Similar to iron and cobalt, it is stable to water and air at room temperature and can resist alkaline corrosion. Therefore, nickel crucibles can be used to melt alkaline substances in the laboratory. Nickel is soluble in dilute acid. Unlike iron, cobalt and nickel react violently with concentrated nitric acid and react slowly with dilute nitric acid.
The value of scrap nickel recycling
With the development of economic construction and the steel industry, nickel is widely used as an alloy element. Stainless steel accounts for more than half of global nickel consumption. Due to the high price of nickel and the continuous reduction of nickel resources, the development of the recycled nickel industry is very important.
Recycled nickel, also known as scrap nickel. About 99% of its raw materials are various forms of nickel-containing scrap from stainless steel, superalloys and batteries. The main sources of nickel-containing waste are "new waste" generated during stainless steel processing and "old waste" generated after stainless steel is scrapped. Industry experts predict that the total amount of nickel-containing waste collected every year is 4.4-4.6 million tons, of which the nickel content is nearly 350,000 tons, which is a quarter of the total demand for nickel.
As the most valuable common non-ferrous metal, the recycling of nickel resources can not only protect the environment, but also turn waste into treasure to avoid the loss of precious nickel caused by landfill, making nickel resources more fully and effectively utilized. At the same time, it also promotes the development of the resource recycling industry. Industries that consume nickel-containing scrap can thus reduce raw material costs by 5%-10%. European scrap recycling levels are higher than those in the Americas and Asia. Developed countries such as the United States and Japan strictly classify and recycle nickel secondary resources, with a recovery rate of more than 80%.
Since nickel is used almost exclusively in the form of alloy products, it is rarely recycled in its pure metal form. Stainless steel accounts for 61% of the world's nickel consumption structure, and nickel for stainless steel in China accounts for 82% of the total consumption. Domestic and foreign countries attach great importance to the recycling of scrap stainless steel, and this industry has become an independent cycle. There are 4-5 international-level scrap nickel processing plants around the world, ensuring that scrap nickel is collected from all over the world. Most scrap nickel originates from stainless steel found in old factories, machinery and consumer products.
