Global MgB2 powder market trend 2024-2026 Is Magnesium Diboride MgB2 a Superconductor? by Newsstrikevector

Russian president demanded that exports of Russian gas to "unfriendly" countries be settled in rubles. The demand has raised concerns in Germany about possible supply disruptions and the impact on industry and households if utilities do not pay in robles. Europe gets about 40% of its gas from Russia. Last year, Europe imported about 155 billion cubic meters. Germany, Europe's largest economy, depends heavily on Russian gas.

The chief executive of Germany's E.ON said the German economy would face "significant damage, which should be avoided if possible" without Russian supplies. He also said it would take Germany three years to wean itself off Russian gas.  

In the event of a supply disruption, Germany's gas network regulator would prioritize home heating over industrial use, so energy-hungry manufacturers such as steelmakers would be the first to suffer, he said.

The volatile international situations will continue to affect the markets and prices of many commodities like the MgB2 powder.

Introduction to Magnesium Boride MgB2 Powder
Magnesium diboride or magnesium boride is an inorganic compound with the chemical formula MgB2. It is a dark gray, insoluble solid. 
The compound is of interest because it becomes superconducting at 39 K (-234 °C). In terms of its composition, MgB2 is significantly different from most low-temperature superconductors, which are mainly transition metals. The superconductivity mechanism is mainly described by BCS theory.
 
Is Magnesium Diboride MgB2 a Superconductor?
The superconducting properties of magnesium diboride were discovered in 2001.
Its critical temperature (Tc) is 39 K (-234°C; -389°F), which is the highest among conventional superconductors. This is unusual in conventional (phonon-mediated) superconductors.  Its electronic structure allows for the existence of two distinct types of electrons at the Fermi level, one of which (sigma-bonding) is more superconducting than the other (Pi-bonding).  This contradicts the usual phonon-mediated superconductivity theory, which assumes that all electrons behave in the same way. The theoretical understanding of MgB2 characteristics can be almost realized by modeling two energy gaps.
In 2001, it was thought to act more like a metal than a cuprate superconductor.

Boron:
Boron (atomic symbol: B, atomic number:5) is a p-block element of group 13 of period 2, with an atomic weight of 10.81. Each boron layer has 2,3 electrons, and its electron configuration is [He] 2s2, 2p1. The boron atom has a radius of 90pm, and the van der Waals radius is 192pm. Boron is classified as a metal-like substance that does not naturally occur on Earth. The element boron, along with carbon and nitrogen, is one of the few elements in the periodic table known to form stable triple bond compounds. The bandgap of boron ranges from 1.50 to 1.56 eV, which is higher than that of silicon and germanium.
 
Magnesium:
Magnesium (atomic symbol Mg, atomic number 12) is the second group S element of period 3, with an atomic mass of 24.3050. The shell electron number of magnesium is [2,8,2] and the electron configuration is [Ne] 3s2. The radius of the magnesium atom is 160pm, and the van der Waals radius is 173pm. Magnesium is the eighth-most abundant element in the earth's crust and the fourth most common on the entire planet. Elemental Magnesium In its elemental form, magnesium has a shiny gray metallic appearance and is a very reactive substance. It can be found in minerals such as brucite, carnallite, dolomite, magnesite, olivine, and talc. Commercially, magnesium is mainly used in the manufacture of strong and light aluminum-magnesium alloys, which have many advantages in industrial applications.

The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.  

The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.  

Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.  

U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.  

The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."  

The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled MgB2 powder are estimated to be influenced by international political situation changes.
