Overview of Aluminum Diboride Powder Aluminum boride (AlB2) is a binary compound formed by aluminum and boron. It is a red solid under normal temperature and pressure. It loses its surface gloss when heated. It is stable in cold dilute acid, and decomposes in hot hydrochloric acid and nitric acid. It is obtained by mixing fine powders of aluminum and boron after heating and reacting. It is one of two compounds of aluminum and boron, and the other is AlB12, which is commonly referred to as aluminum boride. AlB12 is a black and shiny monoclinic crystal with a specific gravity of 2.55 (18°C). It is insoluble in water, acid, and alkali. It is decomposed in hot nitric acid and is obtained by melting boron trioxide, sulfur and aluminum together. The single crystal of AlB2 is parallel to the hexagon of the matrix. Aluminum boride is considered a hazardous substance because it reacts with acid and hydrogen to produce toxic gases. For example, it reacts with hydrochloric acid to release borane and aluminum chloride. The structure of aluminum diboride (AlB2) is similar to that of graphite flakes. There is an Al atom between the B atom and the B atom, which is very similar to the structure of magnesium diboride. The AlB 2 single crystal exhibits metal conductivity along an axis parallel to the hexagonal plane of the substrate. The crystal structure of AlB2 is usually used to describe the prototype structure of intermetallic compounds. There are many structure types in the AlB2 structure family.
What is the applications of Aluminum Diboride Powder The structure of aluminum boride is similar to that of intermetallic compounds, and its structure mainly depends on the crystal structure of aluminum metal and boron rather than their valence relationship. Aluminum borides are AlB2, AlB4 and AlB12. The diboride AlB2 can be generated by the reaction of two elements above 600℃. It is a layered structure, Al atoms are directly overlapped (A, A mode), and B atoms are filled in the triangular column formed by the direct overlap of Al atoms, that is, the boron layer is between the two aluminum layers. [3] The structure of the boron layer is similar to that of graphite. The boron atoms are connected into a hexagonal network. The distance between each B atom and the other three B atoms is 0.173 nm. There are six Al atoms connected to the B, which occupy the vertices of the triangular prism superior. AlB2 can be dissolved in dilute hydrochloric acid to produce a reducing solution, which may contain HB(OH)+3. AlB2 is insoluble in dilute sulfuric acid, but soluble in nitric acid. AlB2 decomposes to form AlB12 above 920°C.
