High Purity Cobalt Co Powder CAS 7440-48-4, 99%
Description of Cobalt Powder :
Cobalt powder, also known as fine cobalt powder or ultra-fine cobalt powder, is a metal powder with unique physical and chemical properties. Its molecular formula is Co, which has a gray, irregular powder form. Among the physical properties of cobalt powder, the most significant is its magnetism. Cobalt is a ferromagnetic metal; its powder form also has this property. This magnetism makes cobalt powder important in manufacturing highly magnetic materials and magnetic recording media. The chemical properties of cobalt powder are also remarkable. It is an extremely reactive metal that reacts with many chemicals, including acids, bases, and some oxidants. When using cobalt powder, attention must be paid to its toxicity. Cobalt and its components can enter the body via the skin or digestive tract and through the respiratory tract and cause adverse health effects. Therefore, relevant operating procedures and safety measures should be followed to avoid unnecessary contact and inhalation.
Application of Cobalt Powder :
With its unique physical and chemical properties, cobalt powder is extensively utilized in a myriad of fields. Some of the main application areas of cobalt powder are described in detail below.
Magnetic materials: Because cobalt is ferromagnetic, cobalt powder is often used to make magnetic materials. Cobalt powder is important in manufacturing high-magnetic materials and magnetic recording media. For example, alloying cobalt powder with other metals can create alloys with specific magnetic properties that can be used to make magnets, magnetic recording media, and so on.
Catalyst: Cobalt powder is a highly efficient catalyst used in many chemical reactions. For example, in the petroleum industry, cobalt catalysts produce high-octane gasoline. In the synthetic ammonia industry, cobalt catalysts are used to increase the yield of ammonia. In addition, cobalt powder can also be used in hydrogenation reactions, oxidation reactions, and many other chemical reactions.
Batteries: Cobalt powder also has important applications in battery manufacturing. For example, cobalt is used as part of the cathode material in lithium-ion batteries. Because cobalt can improve the energy density and stability of batteries, cobalt has an irreplaceable role in battery manufacturing. However, due to cobalt's high price and toxicity, its application in battery manufacturing is also limited to a certain extent.
Tungsten carbide: Cobalt powder also plays an important role in the manufacture of tungsten carbide. Cemented carbide is an alloy made of cobalt and carbide with high hardness, excellent wear resistance, and superior corrosion resistance properties. It is extensively used in production for cutting and measuring instruments, wear parts, etc. Cobalt powder must be mixed with other metal powders and sintered at high temperatures to manufacture cemented carbide.
Coatings and coatings: Cobalt powder can be used as an additive in coatings and coatings to improve their hardness and wear resistance. For example, when making cemented carbide cutting tools, a layer of cobalt powder can be coated on its surface to improve its service life. In the manufacture of decorative coatings, cobalt powder can be added to improve the coating's hardness, wear resistance, and corrosion resistance.
Aerospace field: Because cobalt has high density and good strength and toughness, cobalt powder also has important applications in the aerospace field. For example, cobalt powder can manufacture aircraft engine parts and spacecraft structural parts. Because cobalt has good processing and high-temperature properties, it is also one of the important aviation materials.
Functional materials: Cobalt powder can also be used as functional materials, such as thermoelectric materials, magneto-optical materials, superconducting materials, etc. For example, in thermoelectric materials, adding cobalt can improve the material's thermoelectric properties. In magneto-optical materials, adding cobalt can change the optical properties of the materials. The superconducting properties of superconducting materials can be improved by adding cobalt.

Production Method of Cobalt Powder :
Oxide reduction method: Cobalt oxide and reducing agents such as hydrogen, carbon monoxide, or methane are reduced under certain temperature and pressure conditions to obtain metallic cobalt powder. This method is one of the main methods for industrial production of cobalt powder.
Oxalate thermal decomposition method: heating cobalt oxalate to a high temperature to decompose it into metal cobalt and carbon dioxide. High-purity cobalt powder can be prepared by this method, but the production cost is high.
Electrolysis: A solution containing cobalt ions is energized to obtain metallic cobalt on the cathode. This method can produce high-purity cobalt powder, but the production cost is high, and the waste liquid needs to be treated.
High-temperature thermal dissociation method: Cobalt oxalate is placed in a high-temperature cracking furnace and cracked under closed conditions to obtain metal cobalt powder. The method can prepare high-purity and fine-particle cobalt powder suitable for producing cemented carbide.
Hydrometallurgy: the raw materials containing cobalt and acid, alkali, and other chemical reagents for a reaction so that cobalt dissolved in the solution, and then through extraction, precipitation, crystallization, and other means to obtain metal cobalt. This method can prepare high-purity cobalt powder, but the production cost is high, and attention needs to be paid to waste liquid disposal.
