The roble had hit a record low after the West imposed sweeping sanctions on Russia for its aggression in Ukraine. Russia's president recently ordered exports of Russian gas to "unfriendly" countries to be settled in robles. The speaker of Russia's upper house of parliament said Moscow was prepared and could shift supplies to markets such as Asia if Europe refused to buy Russian energy.
European countries, which pay mostly in euros, say Russia has no right to reset contracts. The G7 rejected Russia's demand and urged companies not to agree to pay in robles, saying most contracts stipulated payment in euros or dollars. Wholesale gas prices in Europe have risen further recently on concerns about potential supply disruptions.
The Kremlin spokesman said, "According to the March 31 deadline set by Russia's president, we are developing all payment methods to get a simple, understandable, and feasible system for relevant European and international buyers,"
The markets and prices of more commodities like the Boron Carbide B4C, Boron Carbide B4C Overview, Boron Carbide B4C Application, Boron Carbide B4C Suppliers, Boron Carbide B4C Price would be affected because of the volatile international political situations.
Overview of boron carbide B4C powder
Boron carbide, also known as black diamond, is an inorganic substance with the chemical formula B₄C, usually a gray-black micropowder. It is one of the three hardest known materials (after diamond and cubic boron nitride) and is used in tank armor, body armor and many industrial applications. It has a Mohs hardness of about 9.5.
Preparation of boron carbide B4C powder
Boron carbide was first reported in the Journal of the American Chemical Society, which was obtained by the reaction of coke and boron oxide in an electric furnace. This preparation method is also the method used in current industrial production.

control nuclear fission
Boron carbide can absorb a large number of neutrons without forming any radioactive isotopes. It is an ideal neutron absorber in nuclear power plants. Neutron absorbers mainly control the rate of nuclear fission. Boron carbide is mainly used in nuclear reactors as controllable rods, but is sometimes powdered due to increased surface area.
During the Chernobyl nuclear accident in 1986, Russia dropped nearly 2,000 tons of boron carbide and sand, which ultimately stopped a chain reaction within the reactor.
Because boron carbide has long been used as a rough grinding material. Due to its high melting point, it is not easy to cast into artificial products, but it can be processed into simple shapes by melting powder at high temperature. For grinding, grinding, drilling and polishing of hard materials such as carbide and gemstones.
Boron carbide can also be used as ceramic coatings for warships and helicopters. It is lightweight and has the ability to resist penetration of armor-piercing projectiles through thermocompression coatings, forming a complete defensive layer.
In the arms industry, it can be used to make gun barrels. Boron carbide, extremely hard and wear-resistant, does not react with acid and alkali, high and low temperature resistance, high pressure resistance, density ≥2.46g/cm3; microhardness ≥3500kgf/mm2, flexural strength ≥400MPa, melting point 2450℃.
Since boron carbide nozzles have the above-mentioned characteristics of wear resistance and high hardness, boron carbide sandblasting nozzles will gradually replace known cemented carbide/tungsten steel and silicon carbide, silicon nitride, alumina, zirconia and other sandblasting nozzles.
Boron carbide is also used in the manufacture of metal borides, smelting sodium boron, boron alloys and special welding.

|Boron 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 Boron Carbide B4C, Boron Carbide B4C Overview, Boron Carbide B4C Application, Boron Carbide B4C Suppliers, Boron Carbide B4C Price is erratic and thus its prices are expected to go higher in the future.
