What is boron carbide used for?

Overview of Boron Carbide

Boron carbide, also known as black diamond, is an inorganic substance with the chemical formula B4C, usually gray-black micropowder. Hard black shiny crystals. The hardness is lower than that of industrial diamond, but higher than that of silicon carbide. More brittle than most pottery. Has a larger thermal energy neutron capture cross section. Strong chemical resistance. Not attacked by hot hydrogen fluoride and nitric acid. Soluble in molten alkali, insoluble in water and acid.

Boron carbide properties

Boron carbide is insoluble in water and organic solvents, has strong chemical stability, is resistant to acid and alkali corrosion, and hardly reacts with all acid and alkali solutions. The thermal neutron capture cross section of boron carbide is large and the neutron absorption ability is strong, so it is called a neutron absorber and a semiconductor.

What are the advantages of boron carbide?

High hardness.

low density.

High melting point.

High elastic modulus.

Chemically inert.

High neutron absorption cross section.

Excellent thermoelectric properties.

Boron Carbide Application

Because of its low density, high strength, good high temperature stability and good chemical stability. It is widely used in wear-resistant materials, ceramic reinforcement phases, especially lightweight armor, and reactor neutron absorbers. Boron carbide B4C powder can replace expensive diamond in some places, and is often used for grinding, grinding, drilling and other purposes.

control nuclear fission

Boron carbide can absorb a large number of neutrons without forming any radioactive isotopes. It is an ideal neutron absorber in nuclear power plants. Neutron absorbers primarily control the rate of nuclear fission. Boron carbide is primarily made into controllable rods in nuclear reactors, but is also sometimes powdered to increase surface area.

Abrasive

Since boron carbide has been used as abrasive a long time ago. Due to its high melting point, it is not easy to cast into artificial products, but it can be processed into simple shapes by melting powder at high temperature. It is used for grinding, grinding, drilling and polishing of hard materials such as cemented carbide and precious stones.

coating

Boron carbide can also be used as ceramic coatings for warships and helicopters.

Due to the above-mentioned characteristics of wear resistance and high hardness of boron carbide nozzles, boron carbide sandblasting nozzles will gradually replace the known ones for cemented carbide/tungsten steel and silicon carbide, silicon nitride, alumina, zirconia and other materials. Sandblasting head.

other

Boron carbide is also used in the manufacture of metal borides and smelting and special welding of sodium boron and boron alloys.
