摘要：
Boron is an atomic species at the origin of the hardest materials. It has one of the most complicated chemistry among the elements. The simplest member of the family, alpha-boron, is based on an arrangement of slightly distorted B-12 icosahedron in a rhombohedral unit cell. It has been studied by x-ray diffraction and Raman scattering up to 100 GPa, showing no sign of phase transformation.
