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