Russian President says if the European Union imposes an oil embargo, Europe will buy energy at the most expensive price and economic activity in Europe will weaken. Rosneft needs to change its business model. Russia will help facilitate settlement and access to loans and insurance in its own currency.
According to Reuters, the European Commission will unveil a 210 billion euro plan on how Europe can end its dependence on Russian fossil fuels by 2027 and use its distance from Moscow to accelerate a shift to green energy. According to a draft document seen by Reuters, Brussels will propose a three-pronged plan to wean countries off Russian fuel: switch to importing more non-Russian gas, move more quickly to promote renewable energy, and work harder to conserve energy. The draft measures, which include EU law, non-binding plans, and possible recommendations by national governments, are subject to change before publication.
Austria is not a member of NATO and will not seek membership in the future, the Austrian Foreign Minister said in Brussels recently. He stressed that it was "their choice" for Sweden and Finland to seek NATO membership, while Austria would remain neutral.
The supply and prices of many other boron carbide powder are expected to continue to be influenced by international situations.
What is Boron Carbide B4C?
Boron carbide, also known as black diamond, is an inorganic substance with the chemical formula B4C. Hard black lustrous crystal.
It has a Mohs hardness of about 9.5, making it one of the three hardest materials known (after diamond and cubic boron nitride). Less fragile than most pottery. Used in tank armor, bullet-proof vests and many industrial applications. Relative density (D204)2.508 to 2.512. Melting point is 2350 ℃. The boiling point of 3500 ℃.
Boron carbide does not react with acid and alkali solution, has high chemical potential, does not react with acid and alkali solution, has high chemical potential, neutron absorption, wear resistance and semiconductor conductivity. It is one of the most stable to acids and is stable in all concentrated or dilute acid or alkaline solutions. Boron carbide is basically stable under 800℃ in the air environment, due to the higher temperature of the oxidation of boron oxide in the gas phase loss, resulting in its instability, oxidation to form carbon dioxide and boron trioxide.
It was discovered in the 19th century as a by-product of research on metal borides and was not studied scientifically until the 1930s. Boron carbide can be prepared by reducing boron trioxide with carbon in an electric furnace.
Because of its low density, high strength, high temperature stability and good chemical stability. In wear resistant materials, ceramic reinforcement, especially in light armor, reactor neutron absorbent applications. In addition, compared with diamond and cubic boron nitride, boron carbide is easy to manufacture, low cost, so it is more widely used, in some places can replace the expensive diamond, common in grinding, grinding, drilling and other applications.
What is Boron Carbide B4C Used For?
Controlled nuclear fission
Boron carbide can absorb large amounts of neutrons without forming any radioactive isotopes, making it an ideal neutron absorber for nuclear power plants, where neutron absorbers control the rate of nuclear fission. Boron carbide is mainly used in nuclear reactors as a controllable rod, but is sometimes made into a powder to increase surface area.
At the Chernobyl nuclear accident in 1986, Russia finally stopped the chain reaction in the reactor after dropping nearly 2,000 tons of boron carbide and sand.
Boron carbide has been used as a coarse abrasive material for a long time. Because of its high melting point, it is not easy to cast into artifacts, but by melting the powder at high temperatures, it can be machined into simple shapes. Used for grinding, grinding, drilling and polishing of hard materials such as hard alloy and precious stone.
Boron carbide can also be used as a ceramic coating for warships and helicopters. It is lightweight and has the ability to resist armor-piercing bullets penetrating the hot-pressed coating as a whole.
It is used in the arms industry to make gun nozzles. Boron carbide, extremely hard and wear-resistant, does not react with acid and alkali, high/low temperature resistance, high pressure resistance, density ≥2.46g/cm3; Microhardness ≥ 3500kGF /mm2, bending strength ≥400MPa, melting point is 2450℃.
Because boron carbide nozzle has the characteristics of wear resistance and high hardness, boron carbide sandblasting nozzle will gradually replace the known carbide/tungsten steel and silicon carbide, silicon nitride, alumina, zirconia and other materials of the sandblasting nozzle.
Boron carbide is also used in the manufacture of metal borides and smelting of sodium boron, boron alloys and special welding.

Gas prices in European countries are expected to triple if Russian supplies are restricted, according to a press release from Rystad Energy, a Norwegian Energy consultancy.
The price of natural gas in Europe was $1,200 per 1,000 cubic meters on Tuesday. The benchmark price is already 300 percent higher than a year ago. European gas prices are expected to continue to soar to $3,500 per 1,000 cubic meters if Russian supplies are restricted, according to Analysis by Monitor.
In 2021, Russia delivered 155 billion cubic meters of gas to Europe, accounting for 31 percent of its gas supply, according to an analysis by Monitor Advisors. It would be difficult for Europe to replace Russian gas, which would also destabilize the global LNG market and have a profound impact on Europe's population and economy.
The analysis also said that if Russia stopped supplies now, Europe's current gas reserves would be exhausted by the end of the year, setting in for a cold winter.
In addition, affected by the geopolitical factors, the supply of the boron carbide powder is erratic and thus its prices are expected to go higher in the future.
