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 known as a gray-black, chemically formula B4C. It is one among the most hardy materials, after diamond and cubic-boron nitride. 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 1930.

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 absorber is responsible for controlling the rate 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 produce and is relatively inexpensive when compared to diamonds and cubic boron triide. Boron carbide’s low price makes it an excellent substitute for diamond 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 absorber material in nuclear reactors. It is a thermal neutron absorber that is efficient, with a thermal cross-section of 347×10-24cm2, which is higher than a few elements, such as gadolinium or samarium. 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 boron carbide ceramic coverings in the nuclear sector and had very positive results.

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 as an abrasive in grinding and polishing engineering ceramics, gemstones, cemented carbide, etc. Boron carbide’s good thermal conductivity as well as good stability in molten iron. 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.
