What is Aluminum Diboride AlB2 Powder?

After Russia pledged to scale back its military operations around Kyiv and in northern Ukraine, the prices of most industrial metals fell, led by aluminum, showing people's concerns for supply shortage eased.

At an earlier time, the West imposed sweeping sanctions on Russia for its invasion of Ukraine, which aroused concerns about the supply problem because Russia is a major producer of nickel, aluminum, and copper. 

Russia is also a major gas supplier to Europe, where potential supply disruptions are seen as hitting power-intensive aluminum and zinc aluminum boride are still very uncertain.

Introduction to Aluminum Diboride AlB2 Powder
Aluminum diboride or Aluminum boride, AlB2 is an inorganic compound with the chemical formula AlB2. It is a binary compound formed by aluminum and boron elements. It is a grey-red solid and insoluble in water at room temperature and pressure. When heated, it loses surface gloss, stabilizes in cold dilute acid, and decomposes in hot hydrochloric and nitric acid.
Aluminum diboride is made by mixing fine powder of aluminum and boron and reacting it with heat. It is one of two compounds of aluminum and boron, the other being AlB12, and they are commonly known as aluminum boride.
Aluminum boride is considered hazardous because it reacts with acid and hydrogen to produce toxic gases. For example, it reacts with hydrochloric acid with borane and aluminum chloride released.
 
Structures of Aluminum Diboride AlB2
The structure of aluminum boride is similar to that of metal interdides in that its structure depends mainly on the crystal structure of aluminum and boron rather than on their valence relationship. The borides of aluminum are AlB2, AlB4, and AlB12. The diboride AlB2 can be formed by the reaction of two elemental substances above 600. It is a layered structure in which Al atoms directly overlap (A, A) and B atoms fill the triangular column formed by the direct overlap of Al atoms, that is, the boron layer is located between the two aluminum layers. The boron layer has a similar structure to graphite. The boron atoms are connected in a hexagonal network. Each B atom is 0.173nm away from the other three B atoms, and six Al atoms are connected to B, which occupy the apex of the triangular column.  AlB2 can be dissolved in dilute hydrochloric acid to produce a reductive solution that may contain HB(OH)+3. AlB2 is insoluble in dilute sulfuric acid but soluble in nitric acid. AlB12 was decomposed by AlB2 at 920

Physicochemical Properties and Applications of Aluminum Diboride AlB2 Powder
AlB2 single crystal exhibits metallic conductivity along an axis parallel to the hexagonal base plane. Boron - aluminum composite aluminum or aluminum alloy reinforced with boron fiber or protective coating boron fiber. The volume content of boron fiber is generally about 45%~55%. It has low specific gravity and high mechanical properties. The longitudinal tensile strength and elastic modulus of the unidirectionally reinforced boron-aluminum composite are about 1.2~1.7GPa and 200~240GPa depending on the process and material. The longitudinal specific elastic modulus and specific strengths are about 3~5 times and 3~4 times of titanium alloy duralumin and alloy steel respectively.  It has good fatigue performance and high strength under 400.
It has been applied to fan blades of turbojet engines and structural parts of aviation, aerospace, and artificial satellites. The hot pressing diffusion bonding method is used to manufacture plate, profile, and more complex shape parts. Continuous casting can also be used to manufacture various profiles.
Aluminum boride can be used in ceramics, medical equipment, nuclear energy, refractory ceramics, and other fields.

The negative electrode material is the carrier of lithium ions and electrons during the charging process of the battery and plays the role of energy storage and release. In the battery cost, the negative electrode material accounts for about 5%-15%, which is one of the important raw materials for lithium-ion batteries. The global sales of lithium battery anode materials are about 100,000 tons, mainly in China and Japan. According to the current growth trend of new energy vehicles, the demand for anode materials will also show a state of continuous growth. At present, the global lithium battery anode materials are still dominated by natural/artificial graphite, and new anode materials such as mesh carbon microspheres (MCMB), lithium titanate, silicon-based anodes, HC/SC, and metal lithium are also growing rapidly.
Our company provides anode materials and aluminum boride. If you need to know more anode materials and aluminum boride, please feel free to contact us.
