  • The red-brown boron-rich solid B7O has been synthesized by means of oxidation of boron with zinc oxide under conditions of 3.5 GPa and 1 200 ℃ for 30 min. The product after leached in hydrochroric acid has been characterized by XRD, XPS, IR, SIMS and chemical analysis. The results of SIMS and chemical analysis show that the chemical formula is B7O. The results of X-ray powder diffraction indicates that the crystal structure of the sample can be classified as hexagonal symmetry with lattice constants of =0.543 5 nm and c=1.2415 nm.
