Boron Carbide B4C Sintering
Boron Carbide(B4C) Products Introduction and Application:
Boron carbide is a hard black metallic shiny crystal, commonly known as black diamond. It is a kind of powdered product that is made of boric acid and carbon material in high temperature smelting in electric furnace and crushed and processed. The theoretical density is 2.52 g/cm3, the melting point is 2450℃, and the microhardness is 4950 kgf/mm2. Its hardness is second only to diamond and cubic boron nitride, and it belongs to superhard material with diamond and cubic boron nitride. With the characteristics of high temperature resistance, acid and alkali resistance, high strength, good chemical stability and light weight, it has been widely used in many new materials fields. Boron carbide is insoluble in water and organic solvents, has strong chemical stability, and resists acid and alkali corrosion. It hardly reacts with all acids and alkali solutions. Boron carbide also has the following characteristics: it has a large thermal neutron capture cross-section, neutron absorption ability, so it is called neutron absorber; and it has the character of semiconductor and so on.
The history of boron carbide: It was discovered in the 19th century as a by-product of metal boride research and was not scientifically studied until the 1930s. Its Mohs hardness is 9.3, it is the third known hardest material after boron nitride and diamond.
Defense industry uses and features:
It can manufacture bulletproof materials, such as bulletproof panels in bulletproof vests, ceramic bulletproof tiles in military aircraft pilot cockpits, and ceramic bulletproof panels for modern armored personnel carriers and tanks. It can be used as a nozzle for making guns and guns in the arms industry. At present, AL2O3-based anti-ballistic ceramics have been used in "502 Projects" and "212 Projects". However, when AL2O3-based ceramic composite armor is used on the sides of vehicles, etc., its weight-reducing effect is not obvious, and the thickness of high boron carbide ceramic composite armor than AL2O3 bulletproof ceramic quality to reduce 15% ~ 20%, and further improve the bullet-proof performance. Therefore, it is urgently required to equip engineering ceramic composite armor development projects with an urgent need for high-performance, low-cost boron carbide ballistic-resistant ceramics. Therefore, the development and application of high-performance, low-cost boron carbide ballistic ceramic materials can greatly improve the performance of related weapons and equipment, and have significant military and economic benefits. The application direction of boron carbide ballistic ceramic materials is: key armored engineering, future main battle tanks, infantry combat vehicles, airdropped airborne vehicles and other light armored vehicles, armored helicopters, and armored superstructures.
