What is Boron carbide?
Boron carbide (B4C) is also called black diamond. It is grayish black, and is a very hard man-made material: Its Morse hardness scale is 9.3, microhardness is 5500~6700kg/mm2, second only to diamond and cubic boron nitride.
Boron carbide structure is hexagonal crystal. Boron carbide density is 2.52g/cm3. Boron carbide melting point is 2450℃, and it decomposes and volatilizes rapidly when the temperature is higher than 2800℃.
 

Boron carbide properties
Boron carbide is insoluble in water and organic solvents, has strong chemical stability, is resistant to acid and alkali corrosion, and does not react with almost all acid and alkali solutions. Boron carbide has large thermal neutron capture cross section and strong neutron absorption capacity, so it is called neutron absorber and semiconductive.
 

What are the advantages of boron carbide?
High hardness.
Low density.
High melting point.
High elastic modulus.
Chemical inertia.
High neutron absorption cross section.
Excellent thermoelectric performance.
 

Boron carbide uses
Because of its attractive combination of characteristics, it is a suitable material for many high-performance applications.
The excellent hardness of boron carbide makes it a suitable grinding powder for grinding, polishing and water jet cutting of metals and ceramics. It is suitable for grinding, polishing, drilling and other processing of all kinds of cemented carbide tools, moulds, parts, components and gemstones. Boron carbide can be made into grinding paste and polishing paste with appropriate amount of oil or water as lubricant.
 
The combination of low specific gravity, high hardness and reasonable toughness makes it a suitable material for car body and vehicle armor.
Boron carbide is also widely used as control rods, shielding materials and neutron detectors in nuclear reactors because it can absorb neutrons without forming long-lived radionuclides.
Because it is a p-type semiconductor, boron carbide can be a suitable candidate for electronic devices that can work at high temperatures.
Boron carbide is also an excellent p-type thermoelectric material.
 
Some typical boron carbide applications include:
Sandblasting nozzle.
Ball and roller bearings.
Sealing parts.
Wire drawing die.
Bulletproof vest
