Abstract
ABSTRACT Two novels boron-rich selenides, orthorhombic B6Se and rhombohedral B12Se, have been recently synthesized at high pressures and high temperatures. Room-temperature compressibilities of these phases were studied in a diamond anvil cell using synchrotron powder X-ray diffraction. A fit of experimental p–V data by the third-order Birch–Murnaghan equation of state yielded the bulk moduli of 155(2) GPa for B12Se and 144(3) GPa for B6Se. No pressure-induced phase transitions have been observed in the studied pressure range, that is, up to 35 GPa.
期刊介绍：
High Pressure Research is the leading journal for research in high pressure science and technology. The journal publishes original full-length papers and short research reports of new developments, as well as timely review articles. It provides an important forum for the presentation of experimental and theoretical advances in high pressure science in subjects such as:
condensed matter physics and chemistry
geophysics and planetary physics
synthesis of new materials
chemical kinetics under high pressure
industrial applications
shockwaves in condensed matter
instrumentation and techniques
the application of pressure to food / biomaterials
Theoretical papers of exceptionally high quality are also accepted.
