Russia's insistence on paying for Russian gas in rubles has rattled European countries: Greece held an emergency meeting of suppliers, the Dutch government would urge consumers to use less gas, and the French energy regulator told consumers not to panic. Russian gas meets one-third of Europe's annual energy needs.

Russia said they could expand their demand for ruble payments for other commodities, including oil, grain, fertilizer, coal, and metals, which raised the risk of recession in Europe and the US. 

Moscow is expected to unveil its ruble payment plan in early April, but it said it would not immediately ask buyers to pay for gas in rubles.  

Western countries have said paying in rubles would be a breach of contract, and renegotiation could take months or longer. This uncertainty has pushed commodity market prices higher.

The supply and prices of other commodities like the Cr3C2 Powder could also be affected.

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.

Southern Copper Corp (SCCO.N) recently said its Peruvian mine remained closed after a six-week standoff with protesters and blamed the Peruvian government for failing to intervene in the safety of its 1,300 workers and their families.  

The company said in a statement that a recent agreement to end protests at the Cuajone mine required the company to withdraw complaints against protest leaders because railways transporting minerals and supplies remained blocked. Production has been suspended since the end of February.  

Peru's Energy Ministry said in a separate statement that it had also reached an agreement with Southern Copper to start talks to find common ground with local communities.  

"If we shut down for a year, the government will stop receiving more than 3.1 billion soles ($830 million) in taxes and royalties, and 8,000 direct and indirect jobs will be lost. This is what we want to avoid, "Southern Copper added in the statement.

Peru has faced a wave of protests from indigenous communities, who accuse mining companies of not providing enough jobs and funding to poor local residents.  

Central bank officials said last week that protests against copper mines such as MMG's Las Bambas and Southern Copper's Cuajone were dragging down the economy.  

Peru is the world's second-largest copper producer and mining is an important source of tax revenue for the country. It is estimated that the supply and prices of the Cr3C2 Powder will be influenced by that.
