Pure 99.95% Cr Chromium Powder Used for Optical Vacuum Coating

Overview Of Chromium Cr Powder

Chromium Cr Powder refers to chromium powder. Due to its unique physical and chemical properties, chromium powder has been widely used in multiple fields. High-purity chromium powder is widely used to produce target materials and superalloys. Target materials are used for sputtering coating and other processes. At the same time, superalloys are alloy materials with excellent high-temperature performance, corrosion resistance, and mechanical properties, commonly used in aerospace, energy, and chemical industries.

Applications Of Chromium Cr Powder

Chromium Cr Powder is an important industrial raw material with many applications. The following are some main application areas of chromium powder:

Anti-corrosion coating: Chromium powder can be used to manufacture anti-corrosion coatings, and its corrosion resistance and stability can effectively protect various equipment from corrosion. For example, coatings made with chromium powder can protect ships and docks from seawater erosion in marine environments.

Wear-resistant materials: Due to the high hardness of chromium powder, it can be used to manufacture various wear-resistant materials. For example, wear-resistant materials made from chromium powder in mines and quarries can protect equipment from wear and tear.

Industrial manufacturing: Chromium powder is also widely used in industrial manufacturing. For example, in manufacturing automobiles and aircraft, chromium powder can produce various components, such as engine parts and brake pads. In addition, chromium powder is also used to manufacture multiple alloys to improve the mechanical properties, corrosion resistance, and high-temperature performance of metal materials.

Pigments and Coatings: Chromium powder can be used as a pigment to give coatings, plastics, and rubber a metallic luster and durability.

Electroplating and welding materials: Chromium powder can be used for electroplating, coating various surfaces to give them a metallic luster and corrosion resistance. It can also be added to welding materials to improve the corrosion resistance and strength of welds.

Other fields: Chromium powder also has applications in catalysts, electrode materials, glass industry, fireworks manufacturing, and motorcycle and automotive parts.

Production Method of Chromium powder

Refine of Decrease:To obtain pure chromium steel, chromium oxide (Cr ₂ O ₃) can be decreased via aluminothermic or hydrogen reduction.

using extreme stress, chromium steel is thawed and afterward spread via a nozzle, simplifying right into a great powder via a procedure that uses either gas or water as the propellant.

Liquify chromium salts in a fluid and pass an electrical current with it, creating chromium to be transferred, which is after that ground right into a powdered kind.

Mechanical Grinding: Grate chromium flakes or chips right into a great powder utilizing a procedure such as sphere milling or different grinding approaches.

Improvement and Classification: Improve the powder and type it based on bit dimension for certain usages.
