Abstract

A multianvil device was used to investigate the formation of B xO phases produced in the 2 to 10 GPa pressure range with temperatures between 1000 and 1800 °C. Amorphous and crystalline B and BP were oxidized using B 2O 3 and CrO 3. Using powder X-ray diffraction and parallel electron energy-loss spectroscopy (PEELS), we were unable to detect graphitic or diamond-structured B 2O, reported in previous studies. The refractory boride B 6O, which has the α-rhombohedral boron structure, is the dominant suboxide in the P and T range of our investigation. PEELS with a transmission electron microscope was used to characterize the boron oxides.
