STRUCTURE OF THE MONOCLINIC MODIFICATION OF RE <sub>3</sub>B
By powder X-ray diffraction the structure of the monoclinic modification of Re <sub>3</sub>B is studied. The phase is obtained under high pressure and high temperature (10 GPa, 1800°C) using nanocrystalline rhenium and amorphous boron. The results of the comparative crystal chemical analysis are reported.
