Introduction to Aluminium Diboride AlB2 powder Aluminum diboride also known as Aluminum Boride, AlB2 (inorganic compound) has the chemical composition AlB2. It is formed from aluminum and other boron elements. It's a gray-red solid that is insoluble at room temperature. The surface gloss of the material is lost when it's heated. It stabilizes in cold dilute acids and then decomposes quickly in hot hydrochloric or nitric acids.
Aluminium diboride can be made from a mixture of fine powdered aluminum and boron, and then it is heated to react with the heat. This is one compound of aluminum and Boron, AlB12 being the other. They are often called aluminum boride.
The reaction of aluminum boride with acid or hydrogen can produce dangerous gases. Aluminum boride can react with hydrochloric Acid to release borane, and aluminum chloride.

Aluminum Diboride AlB2 Structures
In that the structure of aluminum Boride differs from that of metal Interdides, it is primarily dependent on the crystal structure and not on their valence relations, AlB2, AlB4, AlB12 and AlB12 are aluminum's borides. AlB2 diboride can be created by reacting with two elemental substances over 600. It's a layer structure that Al atoms directly overlap. A, A and B fill the triangle column created by Al atoms direct overlap. The boron layers are located between these two aluminum layers. The graphite-like structure of the boron layers is very similar. In a hexagonal network, the boron molecules are interconnected. Every B atom lies 0.173nm apart from all three other B atoms. Additionally, six Al Atoms are connected with B. They occupy the apex portion of the triangular column. Dilute hydrochloric acids can dissolve AlB2 to make a reductive solution, which may include HB(OH!)+. AlB2 cannot be dissolved in dilute sulfuric acids, but is soluble when dissolved in nitric. AlB2 was able to decompose AlB12 at 920.

The Physicochemical and Application Properties of Aluminium Diboride AlB2 Pulp
AlB2 single-crystal exhibits metallic conductivity parallel to the hexagonal basis plane. Boron, aluminum composite aluminum made with boron or protective coating of boron. Boron fibre has an average volume content between 45% and 55%. The specific gravity of boron fiber is low and it has excellent mechanical properties. The composite is unidirectionally reinforced with boron and aluminum and has a longitudinal strength of 1.21.7GPa. It also has an elastic modulus that can be adjusted depending on what process was used. Longitudinal specific elastic modulus, specific strengths and respective specific strength are 35 and 34 respectively for titanium alloy duralumin or alloy steel. It is resistant to fatigue and has high strength, with a limit of 400.
The technique has been successfully used on fan blades in turbojet engines as well structural parts for aviation, aerospace and artificial satellites. For manufacturing plate and profile parts, hot pressing diffusion bonds is employed. You may also make various profiles by continuous casting.
Aluminum Boride can be used for ceramics, in nuclear energy, in refractory and other applications.
