Aluminum diboride
is a binary compound formed by aluminum and boron, its chemical formula is AlB2. Aluminum diboride is a red solid under normal temperature and pressure.
Aluminum boride is one of two compounds of aluminum and boron, the other is AlB12, and they are commonly referred to as aluminum boride. AlB12 is a black and shiny monoclinic crystal with a specific gravity of 2.55 (18degC). It is insoluble in water, acid, and alkali, and decomposes in hot nitric acid. It is obtained by melting boron trioxide, sulfur and aluminum together.
Structurally, B atoms form a graphite-like sheet with Al atoms between them, which is very similar to the structure of magnesium diboride. Single crystals of aluminum diboride exhibit metallic conductivity on an axis parallel to the hexagonal plane of the substrate.
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.
Alumiunm diboride AlB2 can be formed by the reaction of two simple substances above 600. It is a layered structure. Al atoms directly overlap (A, A mode), and B atoms are filled in the triangular pillars formed by the direct overlap of Al atoms, that is, the boron layer is between the two aluminum layers.

Aluminum Diboride Powder Properties
Aluminum diboride loses its surface gloss after heating, and is stable in cold dilute acid, while it decomposes in hot hydrochloric acid and nitric acid. Aluminum diboride is obtained by mixing fine powders of aluminum and boron after heating.Aluminum boride is one of two compounds of aluminum and boron, the other is AlB12, and they are commonly referred to as aluminum boride.

Aluminum Diboride Powder Preparation
Using amorphous boron powder and aluminum powder as raw materials, powder metallurgy is used to prepare AlB12 powder. X-ray diffractometer and scanning electron microscope were used to determine the phase composition, relative content, and microscopic morphology of the product, and the influence of embedding powder on the phase composition of the product was studied, and the optimal process parameters of the synthesis process were determined.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.
