Abstract:

By heating BeB12 with BC13 in a closed tube, Be is substituted by B without changing of the crystal structure. The obtained boron is of 99 purity and tetragonal structure. By this reaction the structural relation between BeB12 and the tetragonal boron modification was proved. IR examinations of alpha-boron, tetragonal boron and BeB12 allowed the assignment of internal vibrations of the B12-icosaedrons and of lattice vibrations. Author
