As the European Union tries to reduce its dependence on Russian energy, the Russian president recently said Russia would try to shift its energy exports to the east, adding that there was no way for European countries to give up Russian gas immediately.
Russia supplies about 40 percent of the EU's gas, and western sanctions imposed over the conflict with Ukraine have complicated financing and logistical arrangements for existing agreements, hitting Russian energy exports, the report noted.
Russia has been building closer ties with China and other Asian countries as the European Union debates whether to impose sanctions on Russian gas and oil and member states seek supplies from elsewhere, Reuters said.
"So-called partners from unfriendly countries admit that they cannot survive without Russian energy, including gas," the Russian president said in a televised government meeting. There is no reasonable alternative to Russian gas in Europe right now."
He also said Europe was driving up energy prices and destabilizing markets by talking about cutting off Russia's energy supplies. Russia, which produces about a tenth of the world's oil and a fifth of its natural gas, will need new infrastructure to increase energy supplies to Asia, he said.
He ordered Moscow to submit a plan by June 1, including "the expansion of transport infrastructure to countries in Africa, Latin America, and the Asia-Pacific region".
He also sought to clarify the possibility of integrating two pipelines -- the Sakhalin-Khabarovsk-Vladivostok gas pipeline in the Far East and the "Power of Siberia" gas pipeline to China -- into Russia's unified gas supply system. In theory, connecting these routes to larger gas networks could allow Russia to divert gas from Europe to Asia.
Because of the ever-changing international situation, the supply and prices of international bulk Cr3C2 Powder are still very uncertain.
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.

Because of the conflict between Russia and Ukraine, there is a shortage of natural gas supply. At the same time, other renewable energy sources cannot produce enough electricity, so electricity prices have soared in many countries of the world. For this reason, I assume the supply and prices of the Cr3C2 Powder would keep being influenced by the high energy prices.
