The crystal lattice of the boron-carbide crystal is D3d5R3m. The rhombohedral lattice can be described as an icosahedron-shaped primitive cell grid that extends diagonally in the space. The c-axis is the same as the diagonal of the area. A linear chain is formed by connecting three boron-atoms to an adjacent icosahedron. Three of the 12 icosahedral position are found on the chain. If B is due to the position of the icosahedron while C is in the linear chain, the stoichiometry is B4C.

1. Basic properties and applications for boron carbide

Low density

B4C density is small at 2.52g/cm3. The empirical formula (9) can be used to express the relationship between carbon content and density in the homogeneous area.

r=2.4224+0.00489C%(9)

Because of the low density of the boron carbide, when the density is increased, the performance of the boron carbide can reach the standard, which means high strength, high toughness, and excellent performance. Therefore, it can be used for lightweight armor in order to reduce the body weight of vehicles and tanks. Save energy.

Hardness and wear resistant

B4C exhibits super hardness, and a high level of wear resistance. B4C’s Vickers Hardness in homogeneous areas increases as the C content increases. The hardness of carbon is 29.1 GPa when carbon is 10.6%. When carbon is 20%, hardness 21 can be as high as 37.7 GPa. At high temperature, its hardness remains high (>30GPa). You can express the change in hardness with temperature by using empirical formula (10).

H=H0-exp(-aT)(10)

The formula is: H0-the hardness of the material at room temperature

Temperature is T.

Carbon is a constant.

This formula applies to 201700. B4C is second only to cubic BN and diamond in terms of hardness.

B4C wear resistance increases with temperature. As the temperature increases, the friction coefficient of B4C decreases. It drops to 0.05 between 20 and 1400, while the friction rate continues to decline. B4C’s super hardness and friction properties have made it a popular nozzle for sandblasting.

What is Boron Carbide?

Boron carburide (also known as black diamand) is an organic material with the molecular formula B4C. It’s a gray-black fine powder. It is among the three hardest substances known (the two others being diamond and cubic boron-nitride). Tank armor, bulletproof vests, and many other industrial uses are made of it. Boron carbide absorbs a lot of neutrons but does not produce radioisotopes. This makes it an ideal neutron absorption material for nuclear power plants. Neutron absorbers are used to regulate the rate of nuclear fusion. Boron carbide, which is used in nuclear reactors, is mostly made into a controlled rod shape. But sometimes it’s made into powder due to the increased surface area.

What are the main applications of Boron Carbide?

(1) The field is national defense. Bullet-proofing has been done with boron carbide ceramics since the 1960s. Comparing it to other materials, its characteristics are easy portability and high toughness. It plays an important role in the lightweight armour of armed aircraft and the bulletproof body armor of helicopters. The British used this material as a raw materials to manufacture armor that can protect against armor-piercing projectsiles.

(2) In terms or chemical raw materials. To increase the wear-resistance and strength of alloys, boron carbide is used as an alloy boronizing agent. This can be done by boronizing the metal to create a thin layer iron boride.

(3) Wear-resistant field. Boron carbide ceramics are visible in a number of industrial nozzles. These include desander nozzles and nozzles designed for high-pressure water gun cutting. They are often chosen by factories for their durability under extreme conditions, and cost-effectiveness. . It can also be used to avoid pollution due to abrasive waste during grinding. As a diamond abrasive substitute, boron carbide can be used to reduce the cost of processing various metals as well as jade glass.

(4) Nuclear energy. Due to its excellent capacity for neutron absorbtion, boron carbide is often used as a neutron absorption control rod, safety rods and in other components, which are designed to reduce the rate of nuclear fusion and ensure human safety.

(5) Aviation. The gyroscope in the navigational system of an aircraft is an essential component. Boron carbide can be used as an additive to increase the gyroscope’s life.

Boron carburide (also known as black diamand) is an organic material with the molecular formula B4C. It’s a gray-black fine powder. It is among the hardest substances known. The other two are cubic boron-nitride and diamond. It’s used in bulletproof vests, tank armor and many other industrial applications. Its Mohs hardness rating is 9.3.

Boron carbide absorbs a large amount of neutrons while forming no radioisotopes. It is therefore an ideal neutron absorption material in nuclear power plants. The neutron absorption materials are primarily used to control the rate at which nuclear fission occurs. Boron carbide, which is used in nuclear reactors, is mostly made into a controlled rod shape. But sometimes it’s made into powder due to the increased surface area.

Due to its low density, it is a good material for lightweight armor and ceramic reinforcement phases. It is widely used in ceramic reinforcing phase, lightweight armor, neutron absorbers and other applications. As boron carbide can be easily manufactured and is less expensive than diamond and cubic Boron Nitride, it is used more often. It can be used in place of expensive diamonds and is often used for grinding, drilling, and grinding.
