Abstract in another language
In the present work we have confirmed the existence of the tetragonal boron phase T-50 that was disputed for more than a half of a century. This phase was reproducibly synthesized at high pressures and high temperatures (HPHT) in the form of single crystals and its structure was refined based on single-crystal synchrotron X-ray diffraction data. We also present here a previously unknown rhombohedral boron phase synthesized in a limited HPHT field. Its structure was solved based on in house single-crystal X-ray diffraction data and found to be similar to that of boron carbide. After hitherto known stable α-B, β-B, and γ-B polymorphs, T-50 and the newly obtained rhombohedral boron phases were designated in the present work as δ-B and ϵ-B, correspondingly. From the experimental evidences, both the phases are considered as metastable.
