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 creating radioisotopes. This makes it an ideal neutron absorber for nuclear power stations. Also, the neutron absorber is responsible for controlling the rate of nuclear fission. Boron carbide can be made into rods for control in nuclear reactors. Sometimes, however, it can also be made into a powder to increase its surface area.
Boron carbide works almost as hard as diamond and boron nutride. However, it is relatively easy to produce and is low in cost when compared to diamond and cubic boron. It is widely used because of its low price, which makes it an excellent substitute for diamonds and boron nutride. 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 water jet cutting and nozzles. Boron carbide, which has excellent corrosion resistance and chemical properties, can also be used to make the shaft tip in rocket liquid fuel flow transmitters. Boron carbide’s good stability to molten steel and thermal conductivity can be used as a continuous 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 can be used for making amorphous carbide coated tools.
