According to statistics from China Chemical and Physical Power Supply Industry Association， China's export volume and export value of lithium-ion batteries have continued to increase. In 2021, China's exports of lithium-ion batteries were 3.428 billion, with a year-on-year growth of 54.34%. The export of lithium-ion batteries was 28.428 billion DOLLARS, up 78.34% year on year.
From the battery export destination, so far. China's lithium-ion batteries are mainly exported to the Asia Pacific and the United States and other places. In terms of price, the price of aluminum boride, led by lithium-ion batteries, is expected to expand globally.
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.
