Rio de Janeiro, Brazil -- Vale today announced that it has completed a pre-feasibility study for its proposed nickel sulfate project in Quebec, Canada, a major milestone in the development of the project. This strategic move demonstrates vale's focus on delivering low carbon and high purity nickel 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:
Bulletproof deck for personal and vehicle
High-pressure water jet cutting nozzle
Scratch-resistant and wear-resistant coating
Cutting tools and dies
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.

Inflationary pressures on Canadians continue to rise. The consumer-price index rose 6.7% in March from a year earlier, the biggest increase since January 1991, according to the latest figures from Statistics Canada.
On a month-on-month basis, Canada's CPI rose 1.4 percent in March, also accelerating from February's 1.0 percent rise.
Prices in the eight major sectors covered by the statistics continued to rise. The uptrend comes against the backdrop of continued price pressures in the Canadian housing market, widespread supply chain constraints, and geopolitical conflicts, according to CBC. A variety of factors have affected energy, commodity, and agricultural markets. Meanwhile, Canada's employment picture continued to improve in March, with the unemployment rate falling to a record low and the average hourly earnings of employees rising.
Excluding gasoline, Canada's CPI rose 5.5 percent year on year in March. It is also the highest since comparable data began in 1999.
The widespread supply chain constraints and geopolitical conflicts are expected to continue to affect the prices of the boron carbide powder.
