High Purity Chromium Carbide Cr3C2 CAS 12012-35-0, 99%

Description of Chromium Carbide Cr3C2 Powder:

High hardness: The hardness of chromium carbide is very high, second only to diamond, with excellent wear resistance and abrasion resistance. Therefore, chromium carbide can be used to manufacture high-performance, wear-resistant materials and surface coatings.

High melting point: The melting point of chromium carbide is up to about 3100 ° C, much higher than most metals and alloys. This gives chromium carbide excellent stability and corrosion resistance at high temperatures.

Thermal conductivity: Chromium carbide has good thermal conductivity, and its thermal conductivity is higher than most metals and alloys. Therefore, chromium carbide can be used to manufacture heat sinks, heat pipes, and other thermal conductivity materials for electronic components.

Good toughness: Compared with other cemented carbides, chromium carbide has good toughness, which makes it able to maintain its wear resistance and abrasion resistance when bearing impact and vibration.

Low coefficient of expansion: Chromium carbide has a low coefficient of expansion, close to that of some advanced ceramics and metal oxides, so it can be used to create coatings and sealing coatings that match these materials.

Good oxidation resistance: At high temperatures, the surface of chromium carbide will form a dense oxide film to prevent further oxidation. This allows chromium carbide to maintain its excellent properties at high temperatures.

Direct carbonization method: chromium powder and carbon black are mixed in a certain proportion, heated to high temperature in an inert gas or vacuum, and direct carbonization is performed. The key to this method is to control temperature and time to obtain chromium carbide with excellent properties. At the same time, in order to prevent deflagration and explosion, the ratio of carbon and chromium and reaction conditions need to be strictly controlled.

Hydrogen carbide method: chromium powder is heated to high temperature with hydrogen and carbon black so that chromium reacts with hydrogen and carbon. This method can obtain high-purity chromium carbide but requires the use of high-purity hydrogen, so the cost is higher. At the same time, in order to prevent hydrogen explosions and air pollution, corresponding safety measures and environmental protection measures need to be taken.

Chlorination reduction method: the chromium salt solution is chlorinated to obtain chromium chloride gas, and then the reduction reaction with carbon at low temperature generates chromium carbide. This method can obtain high-purity chromium carbide but requires the use of chlorinating agents and reducing agents, so the cost is higher. At the same time, in order to prevent chlorine gas leakage and air pollution, corresponding safety measures and environmental protection measures need to be taken.

Chemical vapor deposition method: chromium compounds and carbide raw materials are deposited on the substrate by chemical reaction at high temperatures to produce chromium carbide coating. This method can produce high purity, high density, and uniform structure of chromium carbide coating but requires the use of a high-temperature furnace and other equipment, so the cost is high.

Mechanical alloying method: the chromium powder and carbon black are mixed in a certain proportion, and the chromium carbide powder is obtained by ball milling at high temperatures for a certain time by mechanical alloying. This method can obtain high-purity chromium carbide powder but requires the use of a high-temperature furnace and other equipment, so the cost is high.

A gray powder containing 13.34% Carbon, Chromium carbide, which is insoluble in water and resists acidity, alkali, and phosphorous, has an orthorhombic crystal form. Chromium Carbide density ranges from 6.65 to 6.68 g/cm3, Chromium Carbide melting temperature 1890 degrees; boiling point 3800 degrees. The material has a high melting temperature and is highly resistant to corrosion, wear and oxidation. It can be used in high-temperature environments (1000-1100°C). You can use it as a thermal coating material to protect metal surfaces. It's also used often as a hard alloy. It is used in grain refiners as well as other components that are corrosion and wear-resistant. Chromium carbide-based Cemet exhibits excellent resistance to high temperatures and only lightens slightly after being heated at 982°C for 5 hours. 18-8 stainless-steel has been severely damaged. WC-6Co alloy was also affected.

Wear-resistant materials: Chromium carbide has high hardness and excellent wear resistance and can be used to manufacture wear-resistant materials, such as bearings, gears, tools, etc. In these applications, chromium carbide can significantly improve the wear resistance and service life of the material.

High-temperature structural materials: Chromium carbide has excellent high-temperature properties and can be used to manufacture high-temperature structural materials, such as blades and combustion chambers of aerospace engines. In these applications, chromium carbide can withstand high temperatures and stresses while offering excellent corrosion resistance.

Electronic materials: Chromium carbide has good thermal conductivity and stable electrical properties and can be used to manufacture electronic materials, such as integrated circuit boards, electronic component radiators, etc. In these applications, chromium carbide can improve the reliability and stability of electronic products.

Ceramic materials: Chromium carbide can be used to manufacture ceramic materials, such as high-performance ceramic tools, ceramic balls, etc. In these applications, chromium carbide can significantly improve the hardness and wear resistance of ceramic materials.

Other fields: Chromium carbide can also be used in energy, chemical, and other fields, such as manufacturing solar cell materials, catalysts, and so on. In these applications, chromium carbide can significantly improve material performance and stability.

Cutting tools: Because chromium carbide has high hardness and corrosion resistance, it is widely used in the manufacture of cutting tools. These tools enable efficient cutting on a variety of materials, increasing production efficiency.

Coating material: Chromium carbide can be used as a coating material on various parts surfaces, such as shafts, pistons, and molds. By coating the surface with a layer of chromium carbide, the wear resistance, corrosion resistance, and high-temperature properties can be effectively improved.

Aerospace field: In the aerospace field, chromium carbide is widely used because of its high hardness, high melting point, excellent chemical stability, and good thermal conductivity. For example, it can be used to make gas turbine blades and other high-temperature components for jet engines.

Automotive: In the automotive industry, chromium carbide can be used to manufacture wear-resistant parts and high-temperature structural materials for automotive engines, such as cylinder liners and piston rings. In addition, it can also be used to manufacture coating materials for automotive catalytic converters to improve the performance of catalysts.
