What is Boron Carbide?

What’s Boron Carbide?
Boron carbide (also known as black diamond) is an inorganic compound that can be melted in an electric oven by using boric acid, carbon materials, and high heats in an electric furnace. It is often a grey-black powder and has the chemical formula B4C. It is used to make tank armor and other industrial products. It has an Mohs hardness around 9.5. It was found in 19th-century as a side effect of the research into metal Boride. However, it was only discovered scientifically after 1930s.

Boron Carbide’s Characteristics

Boron carbide features low density, high strength and high-temperature stability. It also has good chemical stability. This is used for wear-resistant materials, ceramic reinforced phase, and especially lightweight armor. Boron carbide has the ability to absorb many neutrons at once without creating radioisotopes. This makes it an ideal neutron absorber in nuclear power stations. Also, the neutron-absorbing element primarily controls the rate and direction of nuclear fission. Boron carbide is mostly made into nuclear reactor controllable rods. But, sometimes, it’s made into a powder in order to increase its surface area.

Boron Carbide has many advantages

Boron carbide works almost as hard as diamonds and boron nutride. However, it’s easy to make and is relatively inexpensive when compared with cubic boron triide and diamond. Boron carbide’s low price makes it an excellent substitute for diamond and/or boron nutride. Therefore, it is widely used. You can use it to replace diamonds in certain places, such as grinding, drilling and other uses.

Boron Carbide is used

1. Nuclear industry: Application of boron carbonide

Boron carbide, which has high neutron absorption and an extensive energy spectrum to absorb neutrons is used often as a neutron-absorbing material in nuclear reactors. The thermal cross-section of the boron-10 Isotope, which has a thermal value as high as 347×10-24cm2, is the highest among them all. This makes it an efficient thermal neutron absorber. Boron carbide, which is abundant in resources, is resistant to corrosion and doesn’t produce radioactive elements, is stable thermally, is non-radioactive, low in secondary ray energy and is highly versatile. This is why it is often used in nuclear reactors as a control and shielding material. Grossman was able to apply a boron carbide ceramic coat to the nuclear industry.

2. Use of Boron carbide in Materials

Boron carbide has a wide range of uses in materials. For example, as an abrasive boron carbide can be used for polishing and grinding engineering ceramics. Boron carbide, which has a high hardness, is used to create sandblasting tools and high-pressure waterjet cutting nozzles. Boron carbide also has excellent corrosion resistance. Boron carbide may be used for the shaft tip in rocket liquid fuel flow transmitters. It can also be used to produce a friction-resistant, corrosion-resistant, and corrosion-resistant part of a ceramic gasturbine. Boron carbide, which has excellent thermal conductivity and good stability in molten iron, so it can be used as an industrial continuous mold. The use of boron carbonide in coatings: Boron carbide is a hard, durable, resistant to radiation, chemically stable, and can be used for making amorphous, boron-carbide coated tools.
