Industrially important metal materials. Cobalt-based wear-resistant alloys that can withstand high temperatures and hard grinding are used in the manufacture of mining equipment, marine diesel engines, aviation engine exhaust valves, etc. In addition, cobalt can also be combined with tungsten carbide.

Tungsten carbide is produced together. It is one of the important components of cobalt-based permanent magnet alloys, and its magnetic field line density is high, and the cobalt content of Anico high-permeability alloys accounts for 25% of cobalt. Low coefficient of expansion alloys are also ideal materials for cobalt. <>

For example, containing2% cobalt alloy, which has the same coefficient of expansion as glass, can be welded in glass and used in appliances, radios, lighting, etc. Blue glass containing cobalt has a high degree of red transparency and is used for flame analysis.

Glass containing cobalt is also used in optical filters and ophthalmic** devices, and cobalt can also be used as a glass color remover. Cobalt oxide is a glaze pigment that is made of a dark blue color by adding 5% cobalt oxide. After the addition of cobalt, the neutralized yellow color of the ceramic turns white, and a high-quality white product is obtained.

Cobalt salts of various organic acids are used as catalysts for polymer synthesis. For example, cobalt acetate is used as a catalyst for man-made fibers, and cobalt naphthalate is used as a paint desiccant.

Co-Mo-Al catalysts are used for hydrogenation and desulfurization. <>

Cobalt salts are essential trace elements for the human body.

One. Cobalt deficiency can lead to decreased appetite, stunting and reduced milk production in cattle and sheep. Vitamins containing cobalt.

2. It can prevent pernicious anemia in humans. An isotope that emits rays.

60 CO, which can be used for physicochemical research and medicine. Cobalt is also used in the surgery. <>

Cobalt is a silvery-white ferromagnetic metal, and cobalt consumed in the form of compounds is mainly used as catalysts, desiccants, reagents, pigments and dyes. It is widely used in biochemistry for activation analysis, etc.

It is a lustrous steel-gray metal. It can be used in the industrial field, it can also be used to make alloys, it can also be used to make pigments, it can also form vitamin B12, and it can also be used to make food.

1. Cobalt-based alloy or cobalt-containing alloy steel is used as blades, impellers, conduits, jet engines, rocket engines, missile parts and various high-load heat-resistant parts and atomic energy in chemical equipment.

Industrially important metal materials.

2. Cobalt as powder metallurgy.

The binder in can guarantee cemented carbide.

There is a certain amount of resilience. Magnetic alloy is an indispensable material in the modern electronic and electromechanical industry, used to manufacture various components of sound, light, electricity and magnetism.

3. Cobalt is also an important part of permanent magnetic alloys. In the chemical industry, cobalt is used not only in superalloys and anti-corrosion alloys, but also in colored glass, pigments, enamels, catalysts, and desiccants.

Chemical properties. Valency of cobalt.

+2 and +3 valence. It does not interact with water at room temperature, and is also stable in humid air. When heated in air to more than 300, it oxidizes to form COO, and when it is white-hot, it is burned to CO3O4.

The fine metal cobalt powder made by the hydrogen reduction method can spontaneously ignite in the air to produce cobalt oxide. As can be seen from the electrode potential, cobalt is a moderately reactive metal.

Its chemical properties are similar to those of iron and nickel. Oxidation occurs at high temperatures. When heated, cobalt reacts violently with oxygen, sulfur, chlorine, bromine, etc., to form corresponding compounds.

Cobalt is soluble in dilute acid and passivated in fuming nitric acid due to the formation of an oxide film. Cobalt is slowly replaced by hydrofluoric acid.

Ammonia and sodium hydroxide.

Erosion. Cobalt is an amphoteric metal.

The above content refers to Encyclopedia-Cobalt.

The metals are as follows:There are more than 100 kinds of cobalt minerals and cobalt-containing minerals found in nature, which belong to 14 categories, including elemental, carbide, nitride, phosphide and silicon phosphide, arsenide and sulfur arsenide, antimony and thioantimonide, tellurium and selenium telluride, sulfide, selenide, oxide, hydroxide and aqueous oxide, hydroxide, hydroxide, hydroxide and silica. Among them, sulfides, arsenides and thieval arsenides are the most.

Introduction:

Cobalt, element symbol CO, silvery-white ferromagnetic metal, silvery-white with a slightly pale pink surface, located in the 4th period, group in the periodic table, atomic number 27, atomic weight, close-packed hexagonal crystals, common valency of +2, +3. Cobalt is a lustrous, steel-gray metal, hard, brittle, ferromagnetic, and disappears when heated to 1150.

It does not interact with water at room temperature, and is also stable in humid air. When heated in air to more than 300, it oxidizes to form COO, and when it is white-hot, it is burned to CO3O4. The fine metal cobalt powder made by the hydrogen reduction method can spontaneously ignite in the air to produce cobalt oxide.

Cobalt is an important raw material for the production of heat-resistant alloys, cemented carbides, anti-corrosion alloys, magnetic alloys and various cobalt salts.

Cobalt is a commonly used metallic element with the element symbol CO.

Cobalt has good magnetic, electrical conductivity and thermal stability, so it has a wide range of applications in industry and scientific research. The main application areas are:

Battery: Cobalt is one of the components of lithium-ion batteries.

Magnetic materials: Cobalt is a key element in the production of high-efficiency magnetic materials.

Chemical industry: Cobalt is widely used as a catalyst in the chemical industry, such as the preparation of epoxy resins.

Cobalt is a silvery-white ferromagnetic metal.

Cobalt, a Chinese second-level character, is pronounced as cobalt (gǔ), a metallic element, with the symbol co, silvery-white. It can be used to make alloys, etc., and is used in medicine with radioactive cobalt (cobalt-60)** malignant tumors. The English name "cobalt" comes from the German kobold, which means "bad elf", because cobalt ore is poisonous, miners and smelters often get sick while working, and cobalt can also contaminate other metals, these bad effects have been regarded as elf pranks in the past.

Cobalt ores are mainly arsenic, oxide and sulfide. In addition, radioactive cobalt-60 can carry out cancer**. Cobalt-60, the radioactive isotope of cobalt, has a wide range of applications in machinery, chemical industry, metallurgy, etc., and can replace radium ** cancer in medical treatment.
