The European Commission has submitted to member states a new draft of sanctions against Russia, including an oil embargo. Some member states that rely heavily on Russian energy sought exemptions.
Western media reported that the European Commission draft of the sixth round of sanctions against Russia includes within six to eight months gradually banning oil imports from Russia, but allowing Hungary and Slovakia to extend the transition period for several months; The Russian Savings bank and other large financial institutions on the sanctions list.
The European Union has imported 44 billion euros of fossil fuels from Russia since Russia launched its special military operation against Ukraine in late February, according to Finland's Energy and Clean Air Research Center.
The Institute for European and Global Economics in Brussels estimates that the European Union currently consumes about $450 million worth of Russian oil a day.
Among EU members, landlocked Hungary and Slovakia, which import most of their oil from Russia, cannot quickly find alternative supplies. Slovakia says the transition will take years. Some officials believe Bulgaria and the Czech Republic may also seek to opt out of oil sanctions against Russia.
Affected by the ever-changing international situation, the supply and prices of international bulk WC powder are still very uncertain.
Introduction to Tungsten Carbide
Tungsten carbide (chemical formula WC) is a compound (especially a carbide) containing equal amounts of tungsten and carbon atoms.
In its most basic form, tungsten carbide is a fine grey powder, but it can be pressed into shape by sintering and used in industrial machinery, cutting tools, chisels, abrasives, armor-piercing bullets, and jewelry.
Tungsten carbide is about twice as hard as steel, with Young's modulus of about 530-700GPa, twice the density of steel - almost halfway between lead and gold.
High strength, high density, and high hardness are the distinguishing characteristics of tungsten carbide, making it a versatile material with a variety of uses. Tungsten carbide can withstand extremely high temperatures, making it an excellent material for machining and cutting tools, even furnaces, and can conduct electricity. Abrasion and corrosion resistance are among the other properties of tungsten carbide.
Tungsten carbide has a high melting point of 2,870 °C (3,140 K). It has a boiling point of 6,000 °C (6,270 K), thermal conductivity of 110W·m (-1) ·K (-1), and thermal expansion coefficient of 5.5μm·m (-1) ·K (-1) at a pressure equivalent to 1 atmosphere (101.325 kpa).
Tungsten carbide is very hard, with a Morse rating of about 9 to 9.5 and a Vickers number of about 2600. It has a young's modulus of about 530-700 gpa, a volume modulus of 630-655gpa, and a shear modulus of 274GPa. Its ultimate tensile strength is 344 MPa, its ultimate compressive strength is about 2.7GPa, and Poisson's ratio is 0.31.
The p-wave velocity (sound speed) through the tungsten carbide thin rod is 6220 m/s.
Tungsten carbide has a low resistivity of about 0.2 µ ω ·m, comparable to some metals, such as vanadium.
Tungsten Carbide VS Diamond
Tungsten carbide is a very hard material. It is predicted to have a Mohs hardness of 8.5 to 9, second only to diamonds. This makes it a valuable metal with many different uses. Tungsten carbide bits are very tough for operations where other metal bits can become blunt and break.
Tungsten Carbide VS Steel
Steel has three times less rigidity than tungsten. This rigidity makes tungsten stronger than steel and titanium. Tungsten is very durable and can withstand many penalties in any job. Whether it's tungsten powder or tungsten carbide blades, this compound gets the job done.
Tungsten Carbide Application
Buildings need to use tools of high strength and toughness so that they can withstand the materials used to form most structures. Materials such as cement and asphalt are difficult to penetrate and require exceptionally durable and strong blades or drills, such as those made of tungsten carbide. Tungsten carbide is commonly used in building materials such as saws and drill bits because it is almost unbreakable.
To make electronics, construction projects, industrial gears, and even aviation equipment, alloys are made by mixing metals with other metals or elements. These alloys have specific properties, such as strength or heat resistance, which are necessary for each product and its use. Alloys made from tungsten carbide are a particularly popular choice for building materials and tools. About 17% of tungsten carbide is used to make these alloys.
Production of surgical tools
Tungsten carbide is commonly used to make surgical instruments because it improves their performance and is resistant to corrosion. It increases the life and strength of surgical tools. The properties of tungsten carbide, such as its ability to sharpen while maintaining hardness, are well suited to the surgical industry.
Because of its durability and strength, tungsten carbide can be used in sports equipment such as golf clubs. It can be used for Musical Instruments such as guitar slides. Another important use of tungsten carbide is for the nibs of ballpoint pens. Tungsten carbide is also used in electrical components, especially light bulbs, because of its heat resistance. Another application of tungsten carbide is in armor-piercing ammunition because it is a durable and tough material. In addition, another interesting and avant-garde application of tungsten carbide is in space satellites, because it can resist extreme temperature fluctuations.
