About Boron Carbide B4C Boride Powder:
Boron carbide formula is b4c, boron carbide properties is low density, high strength, high temperature stability and good chemical stability. Therefore,boron carbide is widely used in wear-resistant materials, ceramic reinforcing phases, especially in lightweight armor, reactor neutron absorbers, etc. In addition, compared with diamond and cubic boron nitride, boron carbide is easy to manufacture and low cost, so it is more widely used. It can replace expensive diamonds in some places and is commonly used in grinding, grinding, drilling and other aspects. If you want to buy boron carbide, please send inquiry to email@example.com
Our company also can supply boron carbide rod, boron carbide sheet.
B4C powder possesses high purity, small particle size distribution, high specific surface area; B4C powder is a synthetic ultra rigid materials, the hardness is 9.46; 56-6200Kg/mm2 microhardness, proportion was 252 g/cm3, melting is 2,250 degrees Celsius.
Chemical properties, non-magnetic, resistant to high and low temperatures, strong acids and alkalis. In addition, boron carbide can effectively absorb neutrons without emitting gamma rays that are harmful to the human body, and it will not form secondary radiation pollution. Feel free to send an inquiry to get the latest price if you would like to buy Boron Carbide B4C Boride Powder in bulk. The hardness is only less than the diamond. Boron carbide is one of the most stable substances to acid, and it is stable in all concentrated or dilutes acid or alkali aqueous solutions. Boron carbide is basically stable below 800°C in an air environment. The boron oxide formed by its oxidation at a higher temperature is lost in the gas phase, leading to its instability and oxidation to form carbon dioxide and boron trioxide.
How is Boron Carbide B4C Boride Powder produced?
Boron Carbide B4C Boride Powder is produced by reducing boron oxide with carbon at high temperatures in an electric furnace. After grinding, the black powder is solidified by pressing at temperatures exceeding 2,000°C (3,630°F). melting point of boron carbide is approximately 2,350°C (4,260°F).

Applications of Boron Carbide B4C Boride Powder:
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 powder 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.
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.
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.
Storage Condition of Boron Carbide B4C powder:
Damp reunion will affect boron carbide ceramics dispersion performance and using effects, therefore, boron carbide B4C powder should be sealed in vacuum packing and stored in cool and dry room, the boron carbide B4C powder can not be exposure to air. In addition, the boron carbide B4C powder should be avoided under stress.
