Application of Boron Carbide B4C Powder:
Boron carbide due to low density, large strength, high-temperature stability, and good chemical stability. In wear-resistant materials, ceramic reinforcement phase, especially in light decoration, reactor neutron absorbers, etc.
Fine and advanced abrasive materials
Because of the high grinding efficiency of boron carbide, it is mainly used as a grinding medium in the grinding process of materials, such as: grinding, grinding, drilling and polishing of hard materials such as gems, ceramics, knives, bearings, and cemented carbides.
Industrial ceramic materials
Products made of boron carbide powder: sandblasting nozzles, sealing rings, nozzles, bearings, plungers of mud pumps, pestles and rocket launchers, ceramic coatings for warships, helicopters, etc., as a new type of material. It has the characteristics of high melting point, high hardness, high elastic modulus, strong wear resistance, and good self-lubricating properties and is widely used in sandblasting machinery, electronics, information, aerospace, automobile and other industries.
Shielding and control materials for the nuclear industry
Boron carbide material has a large thermal neutron capture section, excellent neutron absorption and radiation resistance, and is internationally recognized and recommended as a nuclear reactor control material and shielding material.
Bulletproof armor
Due to its high strength and small specific gravity, it is especially suitable for use in lightweight bulletproof armor, such as the protection of aircraft, vehicles, ships and human bodies.
Improve the life of mechanical parts
Combine boron carbide powder with metal to produce metal-based alloy powder. After special surface treatment of this material, the original mechanical parts are more resistant to wear and corrosion resistance to acid and alkali.
Special absorber provides energy
Boron carbide, also known as "black gold", is used as a power source in powder form as a solid fuel for the rocket.
Chemical industry additives
Due to its stable chemical properties, boron carbide does not react with acid and alkali solutions and has a high chemical potential, so it is widely used in the production of other boron-containing materials, such as zirconium boride and titanium boride.
Advanced refractories
Because of its anti-oxidation and high-temperature resistance, boron carbide is used as a high-grade shaped and unshaped refractory material and is widely used in various fields of metallurgy, such as steel stoves and kiln furniture
