Under the spread of the new crown epidemic, after Americans experienced life and death, they set off the largest "resignation wave" in history, and the number of resignations broke the highest record since statistics began in 2000. Since April this year, more than 4 million people in the United States have voluntarily resigned each month. In August, the number of resignations exceeded 4.27 million, and in November, it rose to 4.4 million. The operation of society is linked. The large number of departures in the United States has led to a large shortage of labor; and the shortage of a large number of labor has directly led to the supply chain crisis in the United States; the supply chain crisis has directly affected prices and prices in the United States. The economy has a direct effect on people's lives.
The economic downturn will affect the market demand for Cr3C2 Powder.
Introduction to Chromium Carbide Cr3C2 Powder
Chromium carbide is an inorganic compound with the molecular formula Cr3C2 and the molecular weight is 180.01. It is gray powder with a rhombic system, A =2.821, B =5.52, C =11.46. The melting point is 1890℃ and the boiling point is 3800℃. The micro-Vickers hardness (load 50 g) is 2700kg/rnrn2, thermal expansion coefficient is 10.3×10-6/K.
It has properties of good wear resistance, corrosion resistance, and oxidation resistance in high-temperature environments (1000~1100℃). It belongs to a type of cermet. Because of its special high-temperature performance, it is widely used as a thermal spraying material for the metal surface protection process and as an additive in cemented carbide industry.
Physicochemical Properties of Chromium Carbide Cr3C2 Powder
Chromium carbide has many excellent properties, such as strong chemical stability, high-temperature hardness, thermal hardness, acid and alkali corrosion resistance, good wear resistance, and it has a high melting point. When chromium carbide is used as inhibitors, it can effectively control the grain growth of cemented carbide.
Moreover, chromium carbide is not only a good abrasion resistance of explosive bonding material additives, but also a high-quality cermet raw material, can also be used as a spraying powder, such as spraying powder at high temperature has good candle resistance, oxidation resistance, and wear resistance. It has been widely used in the metallurgical industry, electronic industry, high-temperature resistant coating, aerospace, and other fields.
In the field of cutting tools, chromium carbide usually plays an important role as a surface coating. In Fe-Cr-c alloy, chromium carbide is an important precipitated phase, which makes the material have excellent wear resistance.

Preparation Methods of Chromium Carbide Cr3C2 Powder
Metal chromium powder carbonization method:
325-mesh metal chromium powder was made by grinding carbon black at 13.5% ~ 64% (mass) ratio (more than the theoretical combined carbon content of 11.33%) with electrolytic chromium, and then used as raw material after dry mixing with a ball mill. Add 1% ~ 3% stearic acid as forming lubricant. Use pressure molding above 1 T/cm2. The pressurized molding powder into the graphite disc or crucible, with Taman furnace or induction heating furnace, in the hydrogen flow (hydrogen dew point at -35℃ or so), heated to 1500 ~ 1700℃, and keep 1h, so that chromium carbonization reaction, chromium carbide generation, after cooling, chromium carbide.
The reaction equation is: 3Cr + 2C → Cr3C2
Applications of Chromium Carbide Cr3C2 Powder
1. Can be used as carbide additives (such as tungsten carbide-based carbide grain refiner), so as to be used in mining, mechanical processing, and other aspects.
2. Can be used as welding material additives. The welding rod made of chromium carbide surfacing welding on the working surface of some mechanical equipment (such as coal mill, ball mill, jaw plate, etc.), can improve the service life of equipment several times more.
3. Used as thermal spraying materials used for metal surface protection process.

Recently, the Turkish government announced that the Turkish President has signed a presidential decree to provide incentives for its Black Sea gas field development projects, including tax exemptions and other preferential measures.
With a fixed investment of 145.1 billion Turkish lira ($10 billion), the project will employ 1,018 people and produce 14 billion standard cubic meters of gas per year, the decree reads. The incentives involved include tariff and VAT exemptions, as well as a range of tax cuts.
In June 2021, Turkish drill ships discovered 135 billion cubic meters of natural gas in the Sakaria field in the Black Sea, bringing Turkey's total gas discoveries in the region to 540 billion cubic meters.
Turkey imports almost all of its annual gas consumption of about 50 billion cubic meters.
Except for natural gas, the supply and prices of many other Cr3C2 Powder will continue to be influenced by international situations.
