What is Boron Carbide Used For?

The US Commerce Secretary has announced that the US will temporarily lift tariffs imposed on Ukraine during the Trump administration to help Ukraine recover its economy and continue to show support for the Russia-Ukraine situation. "For steel mills to remain an economic lifeline for the Ukrainian people, they must be able to export steel," the Commerce Department said in a statement.

The Biden administration will announce the lifting of steel tariffs on Ukraine for one year.  Ukraine is a fairly small supplier of U.S. steel, shipping about 218,000 tons in 2019, ranking it 12th among foreign suppliers to the United States, the report said. The U.S. Commerce Department noted that the steel industry is uniquely important to Ukraine's economic strength, with one in 13 people employed in the steel industry. 

Affected by the ever-changing international situation, the supply and prices of international bulk boron carbide powder are still very uncertain.

What is Boron Carbide B4C?

Boron carbide (B4C) is an extremely hard boron-carbon ceramic and covalent material used in tank armor, bulletproof vests, engine damage powder, and many industrial applications. The Vickers hardness is greater than 30GPa, making it one of the hardest materials known, second only to CBN and diamond. 

Boron carbide is considered to be a robust material with extremely high hardness (Mohs scale of approximately 9.5 to 9.75), high neutron absorption cross-sections (i.e. good shielding against neutrons), and stability to ionizing radiation and most chemicals. Its Vickers hardness (38GPa), elastic modulus (460GPa), and fracture toughness (3.5MPa·m(1/2)) are close to those of diamond (1150GPa and 5.3MPa·m(1/2)). 

As of 2015, boron carbide is the third hardest substance known, after diamond and cubic boron nitride, earning it the nickname "black diamond".

Boron carbide is a semiconductor whose electronic properties are mainly hopping transport.  Band gaps depend on composition and degree of order. The band gap is estimated at 2.09 eV, and there are several middle-band gap states that complicate the photoluminescence spectrum. The material is usually p-type. 

 

What is Boron Carbide Used For? 

Boron carbide is used in refractories because of its high melting point and thermal stability; Because of its extremely strong abrasion resistance, it is used as a grinding powder and coating; High hardness, low density, and excellent ballistic performance; It is commonly used as a neutron radiation absorber in nuclear applications. In addition, boron carbide is a high-temperature semiconductor that can potentially be used for new electronic applications.

 

Specifically, boron carbide can be used as: 

The padlock 

Bulletproof deck for personal and vehicle 

Sandblasting nozzle 

High-pressure water jet cutting nozzle 

Scratch-resistant and wear-resistant coating 

Cutting tools and dies 

abrasive 

Metal matrix composites 

In the brake lining of a vehicle 

Neutron absorber in a nuclear reactor 

High energy fuel for solid fuel ramjets 

 

Is Boron Carbide the Hardest? 

Boron carbide has a Mohs hardness of between 9 and 10 and is one of the hardest synthetic substances known, second only to cubic boron nitride and diamond. 

 

Can Boron Carbide Cut Diamond? 

Due to its high hardness, boron carbide powder is used as an abrasive in polishing and grinding applications and also as a loose abrasive in cutting applications such as water jet cutting. It can also be used for dressing diamond tools.
