What is Boron Carbide?

What is Boron Carbide exactly?
Boron carbide (also known as black diamante) is an inorganic compound that is melted using boric acid and carbon material at high temperatures in an electrical furnace. Its chemical formula, B4C is a gray-black powder. It is used in body armor, tank armor, and many other industrial applications. It has a Mohs Hardness of around 9.5. It was discovered by metal boride researchers in the 19th century. Scientifically, it wasn’t studied until the 1930s.

Boron Carbide’s Characteristics

Boron carbide features low density, high strength and high-temperature stability. It also has excellent chemical stability. It is used in wear-resistant material, ceramic reinforced phases, particularly in lightweight armor, reactor neutralon absorbers, and other applications. Boron carbide can also absorb large quantities of neutrons, without forming radioisotopes. This makes it an ideal neutron absorber in nuclear power stations. Also, the neutron absorber is responsible for controlling the rate of nuclear fission. Boron carbide can be used to make controllable rods for nuclear reactors. Sometimes, however, it is also made into a powder to increase its surface area.

Boron Carbide has many advantages

Boron carbide works almost as hard as diamond and boron nutride. However, it is relatively easy to make and is low in cost when compared to diamond and cubicboron. Its cost advantage makes it an excellent substitute for boron and diamond, so it is much more popular. It is used in certain applications as an alternative to expensive diamonds.

Boron Carbide is used

1. Nuclear industry: Application of Boron carbide

Boron carbide has high neutron absorption and a broad energy spectrum. This makes it a popular neutron absorbing material in nuclear reactors. The thermal cross-section of the boron-10 Isotope is the highest, at 347×10-24cm2. It is a thermal neutron absorber and is second only behind a few elements, such as gadolinium or samarium. Boron carbide has many advantages, including its high resources and resistance to corrosion. It also has excellent thermal stability and does not produce radioactive elements. Also, it has low secondary energy so it is often used in nuclear reactors as a shielding and control material. Grossman applied the boron carbide ceramic coat to the nuclear industry, and obtained very good results.

2. Use of boron carbonide in materials

Boron carbide is a widely used material: boron carbide can be used as an abrasive in the grinding and polishing engineering ceramics. Boron carbide, which has a high hardness, can be used for making high-pressure water jet cutting and sandblasting tools. Boron carbide also has the ability to be used to make high-pressure waterjet cutting and nozzles. Boron carbide, which has excellent corrosion resistance and chemical properties, can be used to make the shaft tip in a flow transmitter of rocket liquid fuel. Boron carbide can also be used to make the shaft tip in a flow transmitter of rocket liquid fuel. Boron can be used as a mold in the machine industry. The use of boron carbonide in coating materials is another option. Boron carbide has a high hardness, wear resistance and radiation resistance and chemical stability. This makes it possible to make amorphous carbide coated tools.
