Aluminium dodecaboride (AlB₁₂) is a chemical compound made from the metal aluminium and the non-metal boron. It is one of two chemical compounds that are commonly called aluminium boride, the other is aluminium diboride, AlB₂.

Properties

There are two crystalline forms, α-AlB₁₂, and γ-AlB₁₂. Both forms are very similar and consist of a framework with three-dimensional networks of B₁₂ and B₂₀ units. ^[1]The phase β-AlB₁₂ is now believed to be the ternary boride C₂Al₃B₄₈.^[2]

Uses

AlB₁₂ is used as a grinding compound to replace diamond or corundum.
