Boron Carbide Properties:

The boron carbide formula is B4C. The boron carbide structure is a hexagonal crystal. Boron carbide density is 2.52g/cm3. The boron carbide melting point is 2450 ℃

Boron carbide hardness: B4C material Mohs hardness scale is 9.3, and its microhardness is 5500~6700kg/mm2, second only to the hardest material diamond and cubic boron nitride.

Boron carbide has the characteristics of low density, high strength, high-temperature stability, and good chemical stability. Therefore, it is widely used in wear-resistant materials ceramic reinforcing phases, especially in lightweight boron carbide armor, reactor neutron absorbers, etc.

In addition, compared with diamond and cubic boron nitride, boron carbide ceramic 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.

B4C powder possesses high purity, small particle size distribution, and high specific surface area; B4C powder is a synthetic ultra-rigid material, the hardness is 9.46; 56-6200Kg/mm2 microhardness, the 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.

Boron carbide is one of the most stable substances to acid, and it is stable in all concentrated or diluted acid or alkali aqueous solutions. Boron carbide is stable below 800°C in an air environment. The boron oxide formed by 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?

In an electric furnace, Boron Carbide B4C Boride Powder is produced by reducing boron oxide with carbon at high temperatures. After grinding, the black powder is solidified by pressing at temperatures exceeding 2,000°C (3,630°F). Its melting point is approximately 2,350°C (4,260°F).

Boron Carbide B4C Powder Uses:

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 high melting points, hardness, elastic modulus, strong wear resistance, and good self-lubricating properties. It 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. It is internationally recognized and recommended as a nuclear reactor control 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 protecting 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 wear-resistant and corrosion-resistant 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. Its high chemical potential is widely used to produce 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, unshaped refractory material. It is widely used in various fields of metallurgy, such as steel stoves and kiln furniture.

Storage Condition of Boron Carbide B4C powder:
