Sweden is in talks with Turkey on joining NATO and looks forward to strengthening cooperation with Turkey in security and counter-terrorism, Swedish Prime Minister Anders Andersson said recently.
Andersson held a joint press conference with visiting European Council President Michel in Stockholm on the same day. Andersson said Sweden is in dialogue with Turkey on joining the TREATY and looks forward to strengthening bilateral relations with Turkey, including cooperation in the areas of security and counter-terrorism. She said Sweden would study a number of issues raised by Turkey.
Speaking at a news conference, Mr. Michel said he believed the Swedish government was taking positive action and taking the necessary steps to reach a solution.
Sweden and Finland formally submitted their applications to NATO Secretary-General Jens Stoltenberg a few days ago. According to protocol, NATO must admit new members by the "unanimous consent" of 30 members.
Turkish Foreign Minister Mevlut Cavusoglu said His country would agree to start NATO talks with Sweden and Finland only if they reach written agreements to stop supporting terrorism and lift restrictions on exporting defense equipment to Turkey, Turkish media reported.
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:
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.

The development of the Russia-Ukraine conflict will continue to dominate the commodity prices such as the boron carbide powder in the future. If the conflict eases or cools, Russia and Ukraine go back to negotiate, commodity prices would fall. However, if the situation between Russia and Ukraine deteriorates further, or evolves into a full-scale war, the price of the boron carbide powder is predicted to see further improvement over the coming days.
