Boron carbide B4C powder characteristics

Overview of Boron Carbide B4C Powder

Boron carbide, also known as black diamond, is an inorganic substance with a chemical formula of B4C, usually gray-black fine powder. It is one of the three hardest materials known (after diamond and cubic boron nitride).

Boron carbide B4C powder 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 carbide 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 B4C powder 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 high temperature oxidation 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.

Characteristics of Boron Carbide B4C Powder

Boron carbide does not react with acid and alkali solutions, and has high chemical potential, neutron absorption, wear resistance and semiconductor conductivity. 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 B4C powder is basically stable below 800°C in an air environment. The boron oxide formed by oxidation at higher temperatures is lost in the gas phase, causing it to become unstable and oxidize to form carbon dioxide and boron trioxide.

The Mohs hardness of boron carbide is about 9.5, which is the third hardest substance known after diamond and cubic boron nitride, and its hardness is higher than that of silicon carbide. Boron carbide B4C powder has the characteristics of low density, high strength, good high temperature stability, and good chemical stability.

Application of Boron Carbide B4C Powder

Control nuclear fission: Boron carbide B4C powder 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 B4C powder 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 B4C powder 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 B4C powder 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 B4C powder is also used to make metal borides and smelt sodium-boron, boron alloys and special welding.
