Properties and applications of boron carbide

Since the beginning of this year, people around the world have felt the pressure of rising prices. Not only the rise in oil prices but also different industries have seen soaring prices. According to the latest data, from August 2021 to the present, the inflation rate in the United States has risen for 6 consecutive months, and this data has soared from the previous 5.3% to 7.9% today. Inflation in the United States, the global Many countries have been affected.
According to experts' forecasts, the inflation rate in the United States may exceed 10% this year, which will face the danger of collapse, which has a great impact on global inflation, including 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.

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.

The EU’s draft REPowerEU plan calls for an increase of 15TWh of rooftop PV capacity by 2022. The draft also calls for EU and national governments to take action this year to reduce the time required to obtain permits for rooftop PV installations to three months, and proposes that "all new buildings and existing buildings with an energy grade OF D or above should have rooftop PV installations by 2025".  

In addition, the European Commission is likely to set a target for installed PV capacity of 300GW by 2025 and 500GW by 2030. Some members are more aggressive, with Austria, Belgium, Lithuania, Luxembourg, and Spain demanding a 1TW target for 2030.  

The REPowerEU initiative, worth 195 billion euros, was proposed by the EU on March 8 to phase out member states' dependence on Russian fossil fuels by 2030. In a few days, the European Commission will present a package to implement the RePowerEU strategy.  

As an important application scenario of distributed PV, rooftop PV is not limited to land, and the development conditions are relatively convenient.  

Since the end of 2021, Spain, France, the Netherlands, and other countries have introduced policies and measures such as government subsidies, tax cuts, fee reductions, and accelerated grid-connection approval to encourage the development of distributed PV.  Europe's potential for rooftop PV is huge and will continue to be an important growth pole for the industry, according to Wood Mackenzie.
