Global BAM powder market trend 2023-2030 What is BAM AlMgB14 Powder? by Newsexpost-news

The roble had hit a record low after the West imposed sweeping sanctions on Russia for its aggression in Ukraine. Russia's president recently ordered exports of Russian gas to "unfriendly" countries to be settled in robles. The speaker of Russia's upper house of parliament said Moscow was prepared and could shift supplies to markets such as Asia if Europe refused to buy Russian energy.

European countries, which pay mostly in euros, say Russia has no right to reset contracts.  The G7 rejected Russia's demand and urged companies not to agree to pay in robles, saying most contracts stipulated payment in euros or dollars. Wholesale gas prices in Europe have risen further recently on concerns about potential supply disruptions.

The Kremlin spokesman said, "According to the March 31 deadline set by Russia's president, we are developing all payment methods to get a simple, understandable, and feasible system for relevant European and international buyers,"

The markets and prices of more commodities like the BAM powder would be affected because of the volatile international political situations.

Introduction to BAM AlMgB14 Powder
Magnesium aluminum boride or Al3Mg3B56, commonly known as BAM, is a compound of aluminum, magnesium, and boron. Its nominal molecular formula is AlMgB14, and its chemical composition is closer to Al0.75Mg0.75B14.
It is a ceramic alloy with very high wear resistance and very low sliding friction coefficient, achieving a record value of 0.04 in the unlubricated state and 0.02 in the lubricated AlMGB14-TiB2 composite.
First reported in 1970, BAM has an orthogonal structure with four icosahedral B12 units per cell. The coefficient of thermal expansion of this super-hard material is comparable to that of other widely used materials such as steel and concrete.
 

Physicochemical Properties of BAM AlMgB14 Powder
Structure
Most super-hard materials have simple, highly symmetrical crystal structures, such as diamond cubes or sphalerite. BAM, however, has a complex, low-symmetry crystal structure, with 64 atoms per cell. The crystal cell is orthogonal and its most prominent feature is four boron-containing icosahedrons. Each icosahedron contains 12 boron atoms.  The other eight boron atoms connect the icosahedron to the other elements in the cell.  The occupancy of metal sites in the lattice is less than 1, so while the material is usually identified by the molecular formula AlMgB14, its chemical composition is closer to Al 0.75 Mg 0.75 B14. Such non-stoichiometry is common for borides (see boride and boron carbide crystal structures for boron-rich metals). The cell parameters of BAM are a = 1.0313 nm, B = 0.8115 nm, C = 0.5848 nm, Z = 4 (four structural units per cell), space group Imma, Pearson symbol oI68, and density 2.59 g/cm 3. The melting point is roughly estimated at 2000 °C.
 
Photoelectric
BAM has a bandgap of about 1.5 eV. Resistivity depends on sample purity and is about 10^4Ohm·cm. The Seebeck coefficient is relatively high, between -5.4 and -8.0 mV/K. This property results from the transfer of electrons from metal atoms to the boron icosahedron, which is beneficial for thermoelectric applications. 
 
Hardness and fracture toughness 
The microhardness of BAM powders is 32-35GPa. It can be increased to 45GPa by nitrization with boron-rich titanium alloy, and the fracture toughness can be improved by TiB2 or by deposition of quasi-amorphous BAM films. Adding AlN or TiC to BAM its hardness will decrease. Hardness values above 40GPa make BAM super hard by definition. In BAM-TiB2 composites, the maximum hardness and toughness are achieved at about 60 vol.% TiB2. By increasing TiB 2 content to 70-80%, the wear rate was improved at the expense of about 10% hardness loss. The titanium B2 additive itself is a wear-resistant material with a hardness of 28-35gpa.
 
Thermal expansion 
The thermal expansion coefficient (TEC, also known as thermal expansion coefficient, COTE) of AlMgB14 was measured as 9 × (10^-6) (K^-1) by expansion measurements and high-temperature X-ray diffraction using synchrotron radiation. This value is fairly close to the COTE of widely used materials such as steel, titanium, and concrete. Based on the reported AlMgB14 hardness value and the material used as the wear-resistant coating itself, the COTE of AlMgB14 can be used to determine the coating application method and the performance of the parts after use.
 
Friction
The composite of BAM and TiB2 (70 % of TiB2 by volume) has one of the lowest friction coefficient values, ranging from 0.04-0.05 in the dry scraping of diamond tips and reduced to 0.02 in water glycol-based lubricants.

BAM AlMgB14 Powder Application
BAM is commercially available and is studying potential applications. 
For example, pistons, seals, and blades on pumps can be coated with BAM or BAM + TiB2 to reduce friction between parts and increase wear resistance. Reducing friction will reduce energy use. BAM can also be coated on cutting tools. The reduced friction will reduce the force required to cut objects, extend tool life, and possibly increase cutting speed.  Coatings only 2-3 microns thick have been found to improve cutting tool efficiency and reduce wear.

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 BAM powder are estimated to be influenced by international political situation changes.
