Now China has become a powerful country in science and technology, but do you know how powerful China's technology is? The manned space station alone is not enough, and now it has successfully broken through the key technology of nuclear fusion, even leading the world by 15 years. Does this mean that China is not far from the artificial sun? It turned out that the fully superconducting tokamak nuclear fusion experimental device developed by China at the Hefei Research Institute of the Chinese Academy of Sciences successfully achieved a record of 101 seconds of continuous operation at 120 million degrees Celsius, and broke the world record. Compared with the previous record in South Korea, China has time has been directly extended by 5 times, and it seems that we are one step closer to the practical stage of artificial sun.
The success of nuclear fusion technology will lead to the development of Cr3C2 powder.
About Chromium Carbide Cr3C2 Powder:
Chromium carbide powder is a very hard refractory ceramic material. It is a fine gray powder and is rarely the natural mineral Tongbaishi. Chromium carbide has strong corrosion resistance and high-temperature oxidation properties, and its thermal properties are similar to steel. It is an excellent material for many commercial industries. Several different chromium carbide compounds can be formed, each of which has slightly different mechanical properties and applications. Chromium carbide is used as a thermal spray material for protecting the underlying metal surface, and as an additive to corrosion-resistant and wear-resistant materials. Chromium carbide applications are particularly effective where sliding abrasion is present. Feel free to send an inquiry to get the latest price if you would like to buy Chromium Carbide Cr3C2 Powder in bulk.
How is Chromium Carbide Cr3C2 Powder produced?
Producing chromium carbide by a combination of aluminothermic reduction and vacuum furnacing at temperatures of 1500°C and above. A blend of chromium metal, chromium oxide and carbon is prepared and then loaded into a vacuum furnace. The pressure in the furnace is reduced and the temperature increased to 1500°C. The carbon reacts with the chromium oxide to form chromium metal and carbon monoxide gas, which is drawn off into the vacuum pumps. The chromium metal then combines with the remaining carbon to form the chromium carbide.
The exact balance between the chromium oxide, chromium metal and carbon determines the grade of chromium carbide that is produced. This is vigorously controlled to ensure that the product quality is suitable for markets as exacting as aerospace.
Performance of Chromium Carbide Cr3C2 Powder :
Chromium carbide, containing 13.34% carbon, is a gray powder, orthorhombic crystal structure, insoluble in water, resistant to acid and alkali. Density is 6.65-6.68 g/cm3, melting point: 1890 degrees, boiling point: 3800 degrees. It is a high melting point inorganic material with good wear resistance, corrosion resistance and oxidation resistance in a high-temperature environment (1000-1100 degrees). It is used as a thermal spray material for metal surface protection and is also often used as a hard alloy. Grain refiners and other wear and corrosion-resistant components. The Chromium carbide-based cermet has excellent oxidation resistance at high temperatures, and the surface is only slightly darkened after 5 hours of heat exposure at 982 °C. Under the same conditions, 18-8 stainless steel has been significantly damaged, and WC-6Co alloy is completely oxidized.

Application of Chromium Carbide Cr3C2 Powder :
Chromium carbide Cr3C2 powder is a high melting point material with good wear resistance, corrosion resistance and oxidation resistance in high-temperature environments. It is made of hard alloy particles made of nickel-chromium alloy and adopts a plasma spraying method, which can be used for high-temperature resistance and wear resistance.
1. Oxidation resistance, oxidation resistance and acid resistance coatings are widely used in aircraft engines and petrochemical machinery and equipment, which can greatly increase the service life of machinery. It is also commonly used as a grain refiner for cemented carbide and other wear-resistant and corrosion-resistant parts. Cermets based on Cr3C2 have excellent oxidation resistance at high temperatures.
2. Used for chromium carbide ceramics. Coarse chromium carbide is used as a melt-blown material to form a melt-sprayed layer on the surface of metals and ceramics, thereby imparting wear resistance, heat resistance, corrosion resistance and other properties to the latter. It is widely used in aircraft engines and petrochemical machinery to greatly increase the life of machinery. It is also used for spraying semiconductor films.
3. As a thermal spray material, used to protect the metal surface below
4. Additives used to manufacture wear-resistant and corrosion-resistant materials
5. As a coating for seals, bearings, valve seals
6. As the microcrystalline phase in cemented carbides (such as vanadium carbide), is used to inhibit the growth of sub-micron grains during pressing and sintering.

Chromium Carbide Health & Safety Information
Recently, the first press conference of the Boao Forum For Asia Annual Conference 2022 was held. Two flagship reports were released at the conference: "Asia's Economic Prospects and Integration Process 2022" and "Sustainable Asia and the World 2022-Green Transformation in Action in Asia".
The flagship report points out that the global economy will recover in 2021, and the pace of economic integration in the Asia-Pacific has not stopped even in the face of the impact of COVID-19. The Asia-Pacific region has provided new impetus for the world's economic recovery and institutional building.
The report gives an outlook on the Asian economy, noting that a number of factors will affect Asian economic growth. For example, mutated strains such as Delta and Omicron have become more transmissible, and many economies are experiencing epidemic peaks again. The Ukraine crisis has triggered geopolitical changes in Asia and Europe, leading to higher commodity prices, which may affect the global energy supply and energy transformation.
The report pointed out that the Asian economy will still be in the process of recovery in 2022, but the growth rate may moderate. According to the report, Asia's economic growth in 2022 is likely to be lower than the current IMF forecast, which is projected at 4.8%.
Affected by several factors, the supply of the Cr3C2 powder is erratic and thus its prices are expected to go higher in the future.
