Recently, the EU proclaimed new sanctions on Russia, including coal, timber, rubber, cement, and fertilizer, as well as high-end seafood boron carbide.

Boron carbide (B4C) is grayish black and is a very hard man-made material. Its Mohs hardness scale is 9.3 and its microhardness is 5500~6700kg/mm2, second only to diamond and cubic boron nitride. The crystal structure of boron carbide is hexagonal crystal.

Boron carbide properties

Boron carbide density is 2.52g/cm3. Boron carbide melting point is 2450℃, and it decomposes and volatilizes rapidly when the temperature is higher than 2800℃. Its linear expansion coefficient is 4.5 × 10-6 / ℃, thermal conductivity is 121.42 W (m ·K), 62.80 W / (m ·K), resistivity is 0.44 (20 ℃) Ω cm, 0.02 (500 ℃) Ω cm.

Boron carbide is resistant to acid and alkali corrosion and is not wetted with most molten metals and has high chemical stability. Boron carbide can resist the oxidation of air at 1000 ℃, but it is easy to be oxidized above 900C in oxidizing atmosphere. Boron carbide powder has a very high grinding capacity, which is 50% higher than that of silicon carbide and 1 / 2 times higher than that of corundum. Boron carbide powder is an excellent grinding material and wear-resistant material.

What is boron carbide used for?

Boron carbide has a unique combination of properties, which makes it the first choice for a wide range of engineering applications.

Boron carbide is used in refractory applications because of its high melting point and thermal stability.

It is used as abrasive powder and coating because of its high wear resistance. It is suitable for grinding, polishing, drilling and other processing of all kinds of cemented carbide tools, moulds, parts, components and gemstones. Boron carbide can be made into grinding paste and polishing paste with appropriate amount of oil or water as lubricant.

It is outstanding in bulletproof performance because of its high hardness and low density.

Boron carbide is also widely used as control rods, shielding materials and neutron detectors in nuclear reactors because it can absorb neutrons without forming long-lived radionuclides.

In addition, boron carbide is a kind of high temperature semiconductor, which may be used in new electronic applications.

Boron carbide can also be used as raw material for manufacturing metal boride, boron alloy, boron steel and so on.

It can be used to manufacture boron carbide hot-pressed products as wear-resistant and high-temperature resistant components, such as nozzles, sealing rings, gyroscopes and petrochemical parts.

Is boron carbide harder than diamond?

The Vickers hardness of boron carbide is more than 30 GPa. Boron carbide is one of the materials with the highest hardness, second only to cubic boron nitride and diamond.

Indonesia plans to increase the content of palm oil-based fuel in biodiesel from 30% to 35%, from B30 to B35, starting from July 20, a senior official from Indonesia's Ministry of Energy said this evening, according to Reuters.

Indonesia, the world's largest palm oil producer, imposed a three-week export ban in May to control domestic cooking oil prices, leading to an increase in palm oil stocks. At present, the authorities are considering reducing the export tax on palm oil to stimulate exports.

Indonesia's Ministry of Energy said that while implementing B35, the ministry will also launch road tests of B40 fuel. Indonesia's senior cabinet minister Luhut Pandjaitan estimates that if Indonesia implements B40, the domestic market may absorb an additional 2.5 million tons of palm oil.

A German government spokesman confirmed that Germany has always wanted Canada to release parts of the "Nord Stream 1" natural gas pipeline sent by Siemens for repair, and this request has received a "positive" response from Canada.

The "Nord Stream 1" natural gas pipeline is the main pipeline for Russia to transmit gas to Europe. At present, the gas output of " Nord Stream 1" has been reduced by 60% compared with the beginning of June, and this is an important time for Germany to store gas for the winter. The German government plans to increase its natural gas inventory to 90% of its gas storage capacity by November, compared with 62% now. Therefore, there is a great need for "Nord Stream 1" gas transmission to fill the inventory.
