Aluminum Diboride AlB2 Powder Properties

About Aluminum Diboride AlB2 Powder:
Aluminum boride chemical formula is AlB2 , so aluminum boride is also called aluminum diboride. It is a binary compound formed by aluminum element and boron elements. Aluminium boride is a red solid under normal temperature and pressure. It loses its surface gloss when heated. It is stable in cold dilute acid and decomposed in hot hydrochloric acid and nitric acid.
Aluminum boride AlB2 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 (18°C). It does not dissolve water. The single crystal of AlB2 is parallel to the hexagon of the base.

Aluminum boride structure is similar to that of graphite flakes. There are Al atoms between B atoms and B atoms, which is very similar to the structure of magnesium diboride. The AlB2 single crystal exhibits metal conductivity along an axis parallel to the hexagonal plane of the substrate.

Aluminium diboride is considered a hazardous substance because it reacts with acid and hydrogen to generate toxic gases. For example, it reacts with hydrochloric acid to release borane and aluminum chloride.

The crystal structure of AlB2 is often used to describe the prototype structure of intermetallic compounds. There are many structure types in the AlB2 structure family.

AlB2 yields a solution having a reducing soluble in dilute hydrochloric acid, and the solution may contain HB (OH), is not soluble in sulfuric acid but can be dissolved in nitric acid. Above 920 degrees AlB2 broken down into AlB12.

Product performance of Aluminum Diboride AlB2 Powder:
Aluminum boride is an ionic compound, with a hexagonal crystal structure. Aluminum boride at an absolute temperature of slightly 40K (equivalent to -233 ℃) will be transformed into a superconductor. And its actual operating temperature is 20 ~ 30K. To reach this temperature, we can use liquid neon, liquid or closed-cycle refrigerator to finish cooling. Compared to the current industry using liquid helium to cool the niobium alloy (4K), these methods are more simple and economical. Once it is doped with carbon or other impurities, magnesium diboride in a magnetic field, or there is a current passing, the ability to maintain the superconducting is as much as niobium alloys, or even better.

How is Aluminum Diboride AlB2 Powder produced?
Amorphous boron powder and aluminum powder are used as raw materials to prepare aluminum boride powder by powder metallurgy.

X-ray diffractometer and scanning electron microscope were used to determine the phase composition, relative content and micromorphology of the product, and the influence of buried 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.

Diboron silane AlB2 indicates that the two elemental substances are formed by the reaction above 600°C. It is a layered structure in which Al atoms directly overlap (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.

The boron layer is similar to the graphite structure. The boron atoms are connected into a hexagonal network. The distance between each B atom and the other three B atoms is 0.173nm. There are six Al atoms connected to B, and they are wrapped on the top of the triangular pillar. AlB2 can be dissolved in dilute hydrochloric acid to produce a reducing solution, which may contain HB(OH)+3. AlB2 does not decompose dilute sulfuric acid but can decompose in nitric acid. AlB2 decomposes to AlB12 above 920℃.

Applications of Aluminum Diboride AlB2 Powder:
Aluminum boride is a random (or rhombic) white or light yellow powder. It can be used as:
Non-toxic flame retardant,
plastics,
rubber,
textiles,
coatings,
superconducting magnets,
transmission lines,
sensitive magnetic field detectors.
