Now China has become a powerful country in science and technology, but do you know how powerful China's technology is? The manned space station alone is not enough, and now it has successfully broken through the key technology of nuclear fusion, even leading the world by 15 years. Does this mean that China is not far from the artificial sun? It turned out that the fully superconducting tokamak nuclear fusion experimental device developed by China at the Hefei Research Institute of the Chinese Academy of Sciences successfully achieved a record of 101 seconds of continuous operation at 120 million degrees Celsius, and broke the world record. Compared with the previous record in South Korea, China has time has been directly extended by 5 times, and it seems that we are one step closer to the practical stage of artificial sun.
The success of nuclear fusion technology will lead to the development of 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:
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.

In a recent speech in Davos, Switzerland, Ukrainian President Volodymyr Zelensky criticized, "My question is: Is there unity in the West? "I don't see it," Zelensky lamented during a video conference from the Davos Economic Forum in Switzerland. "Ukraine needs the support of a united Europe."
"Is there talk of solidarity with Sweden and Finland joining NATO? No." "So is the West united?" Zelensky said at this Ukraine-hosted breakfast in Davos. No." "Our strength is unity within the country," Zelensky said. "Now it depends on the Unity of the West to stand strong and firm behind Ukraine against Russia.
According to Zelensky, "When we are all really united, we will have an advantage over Russia."
Ukrainian President Volodymyr Zelensky says he once again appreciates U.S. President Joe Biden's offer of $40 billion in new financial aid to Ukraine.
"We need the support of a united Europe," Zelensky stressed. Zelensky criticized the position of Hungarian Prime Minister Viktor Orban, who is reluctant to impose an embargo on Russian oil at this stage. "Hungary has a problem!" Zelensky criticized.
