A comparative hardness study of AlB2
What is aluminum boride?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. Aluminum borides are AlB2, AlB4, and AlB12. The diboride AlB2 can be formed by reacting two elemental substances 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 o
