Characteristics of Boron Carbide

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 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 has the characteristics of low density, high strength, good high temperature stability, and good chemical stability.

Boron carbide properties

Boron carbide is a non-metallic material with important physical and chemical properties. After boron nitride, it is the hardest boron compound. Its high melting point, large neutron capture surface, low density, chemical inertness, excellent thermal and electrical properties This makes boron carbide a new high-tech material. Boron carbide can also be added to alumina and silicon carbide ceramics, which can improve the fracture toughness of the material and increase its strength relatively; because boron carbide can also absorb a large amount of neutrons, so The application of boron carbide is more extensive.

Boron carbide is a high-temperature P-type semiconductor material. It has excellent properties such as strong hardness, low density, and high chemical inertness. It can react with metals such as Fe, Ni, Ti, zr, etc. at a high temperature of 1000C. In addition, due to atoms It has a strong ability to absorb neutrons, so boron carbide has good applications in atomic physics and medicine. In addition, boron carbide is also widely used in microelectronics, nuclear physics, military and space technology due to these properties. application.

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.

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 high-temperature oxidation is lost in the gas phase, making it unstable, and oxidizing to generate 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: 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 gemstones.

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 to form an overall defense layer.

Nozzle: Boron carbide 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.
