Boron Carbide Properties:
Boron carbide has the formula B4C. Boron carbide crystals are hexagonal. Boron carburide density has a value of 2.52g/cm3. Boron carbide has a melting point of 2450
Boron carburide hardness (B4C): Mohs hardness is 9.3; its microhardness ranges from 55006700kg/mm2, making it second only after the hardest material cubic boron-nitride and diamond.
Boron carbide is known for its high strength, low density and high temperature stability. It also has a good chemical stability. Boron carbide is widely used as a ceramic reinforcement phase, in particular in lightweight armor and reactor neutron absorbers.
ceramic boron carbide has a lower cost and is easier to manufacture than diamond or cubic boron. It is used more often. It is a good alternative to diamonds, which are expensive.
B4C powder is high-purity, has small particle sizes, and high specific surfaces. B4C, on the other hand, is an ultra rigid material, with a hardness of 9.46. It also has microhardnesses between 56-6200Kg/mm2, a proportion of 252 g/cm3, a melting point at 2,250 degrees Celsius.
Chemical properties: resistant to strong acids, alkalis, and high and low temperature. It can also absorb neutrons and emit gamma-rays, which are harmful to human health.

Boron carbide is a very stable substance in acidic solutions. It is also stable in alkaline or concentrated acidic aqueous solution. Boron carbide remains stable in an atmosphere below 800degC. The boron oxide that is formed when it is oxidized at higher temperatures, is lost in gas phase. It then oxidizes into carbon dioxide and borontrioxide.
How is Boron Carbide produced
Boron Carbide (B4C) Boride Powder is created by reducing carbon with boron at high temperatures using an electric furnace. After grinding the black powder, it is solidified through pressing at temperatures above 2,000degC. Its melting temperature is about 2,350degC.

Boron Carbide B4C Powder Uses:
Fine abrasive and advanced materials
It is used in grinding processes for hard materials, including gems. ceramics. knives. bearings.
Industrial ceramics
The following products are made from boron-carbide powder as a novel material: sandblasting nodes, seal rings, nozzles bearings plungers of mud pump, pestles rocket launchers and ceramic coatings for helicopters or warships. It has high melting points, high hardness and high elastic modulus. It also has good wear resistance and self-lubricating qualities.
Materials for shielding and controlling the nuclear industry
Boron carbide is a highly regarded material that has been internationally recognized for its neutron absorption properties, thermal neutron capture, and radiation resistance.
Bulletproof armor
Due to its strength and low specific gravity, it's especially suitable for use as lightweight bulletproof armour, such as protecting aircraft, vehicles, vessels and human body.
Improve mechanical part life
Mix boron-carbide powder with metals to create metal-based alloy powder. After a special treatment, original mechanical components are more resistant to corrosion and wear.
Special absorber provides energy
The solid fuel rocket uses boron carbide (also known as black gold) as an energy source.
Chemical additives
Because of its high chemical potential and stable chemical properties, it is widely used for the production other boron-containing material, such as titanium boride or zirconium.
Advanced refractories
It is widely used to make steel stoves, kiln furniture, and other metallurgical products.
Storage condition of Boron Carbide powder B4C:
B4C Powder dispersion and use effects will be affected by damp reunion. Therefore, the B4C Powder should be packed in vacuum and kept in a dry and cool room. In addition, boron carbide powder B4C must not be exposed to stress.
Shipping & Packing of Boron Carbide (B4C) powder:
The amount of B4C powder we use will determine the type of packing.
Boron carbide powder packaging: vacuum packed, 100g,500g or 1kg/bag; 25kg/barrel.
Boron carbide B4C Powder Shipping: Could be shipped by air, by sea or by express as soon after payment receipt.
