Gazprom recently said it had completely suspended gas supplies to Bulgarian Gas company and Polish Oil and Gas Company (PGNiG) because it was not being paid in rubles.  Russia said it would resume gas supplies after it agreed to pay for them in rubles.  

Bulgaria and Poland announced Monday that they have received a notice from Russia to suspend natural gas supplies from Monday.  

Russian President Vladimir Putin on March 31 signed a presidential decree to settle gas trade with "unfriendly" countries and regions in rubles.  When the new rules took effect on April 1, Presidential press secretary Dmitry Peskov said Russia would not immediately "cut off gas" to Europe, as the cost of gas supplies starting April 1 should be settled in the second half of April or May.  

Because of the ever-changing international situation, the supply and prices of international bulk Boron Carbide B4C powder,Overview of Boron Carbide B4C powder,Application of boron carbide B4C powder,Boron carbide B4C powder price,Boron Carbide B4C Powder Supplier are still very uncertain.

Overview of Boron Carbide B4C powder

Boron carbide (B4C) is also known as black diamond. It is gray-black and is a very hard man-made material: the Mohs hardness is 9.3, and the microhardness is 5500~6700kg/mm2, second only to diamond and cubic boron nitride.

The structure of boron carbide is hexagonal. The density of boron carbide is 2.52g/cm3. The melting point of boron carbide is 2450℃, and it decomposes and volatilizes rapidly when the temperature is higher than 2800℃.

 Boron carbide B4C powder properties

Boron carbide is insoluble in water and organic solvents, has strong chemical stability, is resistant to acid and alkali corrosion, and hardly reacts with all acid and alkali solutions. The thermal neutron capture cross section of boron carbide is large and the neutron absorption ability is strong, so it is called a neutron absorber and a semiconductor.

Application of boron carbide B4C powder

Due to its attractive combination of properties, it is a suitable material for many high-performance applications.

The excellent hardness of boron carbide makes it a suitable abrasive for grinding, polishing and water jet cutting of metals and ceramics. It is suitable for grinding, polishing, drilling and other processing of various carbide tools, molds, parts, components and gemstones. Boron carbide can be made into abrasive paste and polishing paste with appropriate amount of oil or water as lubricant.

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.

Abrasives

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.

Coating

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.

Nozzle

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.

Other

Boron carbide is also used in the manufacture of metal borides, smelting sodium boron, boron alloys and special welding.

Ukrainian media recently reported that Ukraine will build a food transfer station in the Chernovze region, and the first phase is scheduled to be completed by the end of 2022. According to reports, the completion of the project will help ease the current congestion in grain shipments, and it is estimated that the transfer station will be able to handle 3 million tons of grain per year and store up to 200000 tons of grain at the same time.


According to the Cuban Electric Union on August 8, affected by the fire at the oil reserve base in Matansas province, the Antonio Guiteras thermal power plant near the oil storage base stopped operation at about 13:00 local time. It is reported that the shutdown of the thermal power plant is due to water shortage, and although measures have been taken to supply water to the plant through pipelines, it is still not enough to maintain its operation. The Cuban electricity Union said it could not guarantee that the thermal power plant would resume operation during peak hours.


According to a monthly monitoring report released by the Copernicus Climate change Service, an EU climate monitoring agency in Bologna, Italy, in July 2022, the Antarctic sea ice area was the lowest in 44 years of satellite monitoring records, 7% lower than the average.
