Aluminum Boride
?
Aluminum boride can be described as a binary mixture of aluminum and Boron. AlB2 is its chemical formula. The chemical formula is AlB2. It’s a reddish solid at normal temperatures and pressures. The surface luster of the material is lost when it’s heated. It’s stable in cold dilute and it breaks down in hot hydrochloric or nitric. After mixing fine powders, aluminum and boron are heated and react to form.
Aluminum Boride: The Characteristics
Aluminum Boride (black glossy monoclinic crystal) has a specific gravity of 2.55 (18degC), is insoluble and acid- and alkali insoluble, and can be made by melting aluminum trioxide and sulfur together. The reaction of aluminum boride with acid or hydrogen can produce dangerous gases. Aluminum boride reacts with hydrochloric to release borane or aluminum chloride. In structure, the B atoms create graphite sheets that look like sheets and have Al atoms in between. This is very similar with magnesium diboride’s. AlB2 is a single crystal that exhibits metallic conductivity with an axis parallel the hexagonal plan of the substrate.

How to prepare aluminum iboride
AlB12 powder was produced by powder metalurgist. To determine the composition of the product and its relative contents, the X-ray scattering microscope and the scanning electron microscope were employed. Results show that product impurities can be determined by their buried powder Al content. The buried powder Al content is 30% (mass content, the same below), and elemental Al exists in the product; the buried powder Al content is 10%, and the impurities are mainly Al2O3; When the Al content of the buried powder is 20%, the impurity content is the least, which is mainly oxy-magnesium-aluminum phase. The optimal conditions for synthesizing are: constant temperature of 1400°C, 60 minutes, an Al content of 17.2% and 20% buried powder.
Aluminum Boride: What are its applications?
AlB2 and AlB4 are similar in structure to intermetallic compound. The aluminum boride structure is mainly dependent on crystal structure and not their valence relation. AlB2, AlB4, and AlB12 are aluminum borides. AlB2 is a diboride that can be created by the combination of two elements greater than 600. It has a layer structure. Al and B atoms directly overlap (A, A mode), with the Triangular Column formed by Al atoms. This means that the boron layers are between the Al atoms. The structure and function of the boron layer are similar to that found in graphite. These boron molecules are linked into a hexagonal network. Distance between the B atoms and other B atoms is 0.1773 nm. The six Al atoms that are linked to the B are found at the vertices the triangular prism inferior. Dilute hydrochloric Acid can dissolve AlB2 to make a reducing mixture, which could contain HB (OH)+. AlB2 cannot be dissipated in dilute sulfuric acids, but is soluble when dissolved in nitric. AlB2 will eventually decompose to AlB12 if it reaches 920C.
