Aluminum boride AlB2 (or AlB2) is a binary mixture made of aluminum and boron. It is a red solid at normal pressure and temperature. It loses its glossy surface when heated. It is stable when it is in cold dilute acid. However, it will decompose in hot hydrochloric or nitric acid. Mixing fine powders of aluminum or boron and heating them after reacting.
It is one among two compounds of aluminum, boron and AlB12, also known as aluminum boreide. AlB12, a black, shiny monoclinic crystal, has a specific gravity of 2.55 (18degC). It is insoluble when it comes into contact with acid, water, and alkali. It is formed by melting aluminum, sulfur and boron trioxide. AlB2 has a single crystal that is parallel to the hexagonal structure of the matrix.
Because aluminum boride reacts with acid or hydrogen to make toxic gases, it is classified as a dangerous substance. To release borane, and aluminum chloride, it reacts to hydrochloric acid.
AlB2 (alluminium diboride) has a structure that is very similar to graphite flakes. It is found between the B and B atoms of aluminum diboride (AlB2), which is very similar with the structure in magnesium diboride. AlB 2 single crystal shows metal conductivity along an angle parallel to the hexagonal plan of the substrate.
The prototype structure for intermetallic compounds is usually described by the AlB2 crystal structure. There are many structures in the AlB2 family.
Aluminum boride can be described as a light yellow, white, or random-colored powder. It can be used in the following ways:
Flame retardant non-toxic
Magnets with superconductivity
Magnet field detectors that are sensitive.
