Since the beginning of this year, people around the world have felt the pressure of rising prices. Not only the rise in oil prices but also different industries have seen soaring prices. According to the latest data, from August 2021 to the present, the inflation rate in the United States has risen for 6 consecutive months, and this data has soared from the previous 5.3% to 7.9% today. Inflation in the United States, the global Many countries have been affected.
According to experts’ forecasts, the inflation rate in the United States may exceed 10% this year, which will face the danger of collapse, which has a great impact on global inflation, including boron carbide powder.
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.

With Russia taking the lead on Poland and Bulgaria at the end of last month, there appears to be a growing sense of compromise within the EU over whether to accept Moscow's proposed rouble settlement order.
Italy's prime minister said recently that European companies would be able to buy gas in roubles without violating sanctions. This apparently ignores the guidance of hardliners in the EU to "fight to the end".
For weeks, European companies have been trying to find ways to meet Russia's payment demands for the rouble while maintaining vital gas supplies without violating sanctions against Moscow.
Late last month, European Commission President Von der Leyen said operating under the mechanism would violate sanctions and asked European companies not to bow to Russian demands. However, the EU has yet to issue more rigorous written guidelines on how companies should pay Gazprom.
The Italian prime minister said recently, "There is no official announcement from the European Union about what ruble settlement means for sanctions violations, and no one has said whether ruble payments violate sanctions or not. It's a grey area."
"In fact, most gas importers are already opening rouble accounts for deals with Gazprom,"
He also used German companies as a shield. He said Germany's largest gas importer had already paid in rubles. "In fact, we saw evidence yesterday that the largest gas importer in Germany has already paid in rubles."
