Boron carbide (B4C)-about applications of boron carbide

Characteristics of boron carbide B4C powder

Boron carbide B4C powder does not react with acid and alkali solutions, and has high chemical properties, neutron absorption, abrasion resistance and semiconductor conductivity. It is one of the most stable substances to acid, stable in all concentrated or dilute acid or alkali solutions. When some transition metals and their carbides coexist, they have special stability. The transition metals IV, V and VI of the periodic table react strongly with metal borides at 1000-1100°C to form boron carbide metal B4C powder. With a hardness of 9.3, it is the third largest known substance after diamond and boron nitride B4C powder.

Overview of boron carbide B4C powder

Boron carbide has the characteristics of low density, high strength, good high temperature stability, and good chemical stability. Therefore, it is widely used in wear-resistant materials, ceramic reinforcement phases, especially lightweight armor, reactor neutron absorbers, etc. In addition, compared with diamond and cubic boron nitride, boron carbide is easy to manufacture and low in cost, so it is more widely used. In some places, it can replace expensive diamonds, usually used for polishing, grinding, drilling, etc.

Boron nitride B4C powder has the characteristics of high purity, small particle size distribution, and large specific surface area. B4C powder is a synthetic superhard material with a hardness of 9.46; a microhardness of 56-6200Kg/mm2, a ratio of 252g/cm3, and a melting point of 2250 degrees Celsius.

Chemical characteristics, non-magnetic, high temperature and low temperature resistance, strong acid, strong alkali. In addition, boron carbide can effectively absorb neutrons, does not emit gamma rays harmful to the human body, and does not form secondary radiation pollution. The hardness is only lower than diamond. Boron carbide is one of the most stable substances to acid, and it is stable in all concentrated or dilute acid or alkali aqueous solutions. Boron carbide is basically stable below 800°C in an air environment. The boron oxide formed by oxidation at high temperature is lost in the gas phase, making it unstable and oxidized to form carbon dioxide and boron trioxide.

Boron carbide can absorb a large number of neutrons without forming any radioactive isotopes. It is an ideal neutron absorber for nuclear power plants. Neutron absorbers mainly control the rate of nuclear fission. Boron carbide is used in nuclear reactors. Made into controllable rods, but sometimes made into powder due to increased surface area.

Application of boron carbide B4C powder

Control nuclear fission: Boron carbide can absorb a large number of neutrons without forming any radioactive isotopes. It is an ideal neutron absorber for nuclear power plants. Neutron absorbers mainly control the rate of nuclear fission. Boron is mainly made into controllable rods in the field of nuclear reactors, but sometimes it is made into powder due to the increase in surface area.

Abrasive: Because boron carbide has been used as a coarse abrasive for a long time. Because of its high melting point, it is not easy to cast into artificial products, but the powder can be smelted into simple shapes. high temperature. Used for grinding, grinding, drilling and polishing hard materials such as cemented carbide and gems.

Coating paint: Boron carbide can also be used as a ceramic coating for warships and helicopters. It is light in weight and can resist the penetration of armor-piercing projectiles through the hot-press coating, forming an overall defense layer.

Nozzle: It can be used as a spray gun nozzle in the ordnance industry. Boron carbide is extremely hard and wear-resistant, does not react with acid and alkali, is resistant to high temperature/low temperature, and is resistant to high pressure. Boron carbide is also used to make metal borides and smelt sodium-boron, boron alloys and special welding.
