Aluminium diboride (AlB2) is a chemical compound made from the metal aluminium and the non-metal boron. It is one of two compounds of aluminium and boron, the other being AlB12 that are both commonly referred to as aluminium boride.
Structurally the B atoms form graphite like sheets with Al atoms between them, and this is very similar to the structure of magnesium diboride. Single crystals of AlB2 exhibit metallic conductivity along the axis parallel to the basal hexagonal plane.[1]
Aluminium boride is considered a hazardous substance as it reacts with acids and hydrogen gas to produce toxic gases.
